A figure has 2 sides of parallel sides and 4 right angles All of the sides are the same lenght What are the 3 names for the figure?
The 3 names for this figure are: 1. Square - all sides are parallel, there are 4 right angles, and all the sides are the same length. All squares are quadrilaterals and parallelograms. 2. Quadrilateral - 4 sides. NOT all quadrilaterals are squares, however. 3. Parallelogram - all sides are parallel. NOT all parallelograms are squares, however.
How do calculators calculate Sin Cos and Tan of an angle without side lengths?
The relationship between an angle and the triangle formed by it is always constant. This is also why sin cos and tan obtained from the unit circle can be applied to all triangles with the same angle. All that matters is the ratio of the sides, so the calculator can "pick" any length for one side, and use that and the angle to find the other side(s). This answer will be the same regardless of which triangle you are specifically referring to. Side lengths 3 and 5 will produce the same trig values as sides 21 and 35. Also, given the processing power of most calculators, these values are often programmed in, similar to how many students are "programmed" to know the trig values for major angles such as pi, pi/4, 30deg, and 60deg.
Definition of complement of a set?
S', the complement of a set S, in the context of the universal set U, is the set of all elements of U that are not in S. It is important to note that a complement is defined only in terms of the universal set. The following, rather crude example illustrates the point. Suppose S is the set of all boys. Then S' may be the set of all girls if U = youngsters; or S' = set of all girls, women and men if U = people; or S' = set of all girls, women, men, dogs, cats, cows, ... if U = mammals; and so on. As you see, changing U alters S'.
What is another word for an equalateral triangle?

How do you build triads in the key of A minor?
Quite the same way you would in any other minor key. In a minor key, the chords are as follows: i iidim III iv V VI VII. So, naturally, following the rules of building triads, one would build a minor triad for i, a diminished triad for ii, major for III, minor for iv, major for V, Vi, and VII. So, "i" would look like this: Root-->third-->fifth. Because it is a minor triad, the third is a minor third up from the root, and the fifth is a pefect fifth up from the root. So, in A-minor, the 'i' triad would be A(root), C(third), E(fifth). The same applies to all minor chords. The diminished chord is similar, but both intervals are minor thirds, rather than a minor third and a major third. So, in A-minor, that would be B, D, F. Major chords are the opposite of minor chords, the structure being major third, then minor third, rather than minor third, then major third. Hope this helps, let me know if there is anything I can clear up for you. Cheers, Dan
How is it that a song can use a major chord on the supertonic degree so that I have G F D and C major chords in the same song?
The major II chord (whose root is the supertonic) is actually a temporary modulation to the key of the Dominant, and is called a secondary dominant. Given your chords I'm assuming we are in C Major, which already has the major I, IV and V triads (the chords C, F and G). The two, three and six chords are normally all minor (IIm, IIIm and VIm or in C Major: Dm, Em and Am). In C Major, the minor two triad (IIm in jazz / ii in classical) consists of the notes D, F and A, but here the D major triad has an F# instead of the F natural as it's third. One of the things that happened to music when harmony became part of it, about five centuries ago, was the ability to change keys. The Baroque and Classical mentality was to present a theme in the home key and then at some point modulate to the dominant and subdominant or to the relative minor or tonic minor and then eventually modulate back to the home key. Over time, the idea of modulating to a different key has been modified to just "borrowing" a chord or two from another key. That's basically what's happening when you use a Major II chord. The raised F to F# in C Major is actually the proper Leading Tone of the key of G Major (it's "ti" note). If we were in the key of G major, that D triad (the V triad) would be the notes D, F# and A - the dominant chord. Notice also that G is the dominant of C major. So the D major triad in the key of C Major is the dominant of the dominant. We have temporarily modulated to the key of G major and used its dominant chord (the D major triad), which is usually followed by the G chord, making a proper V-I cadence in the key of G Major. The G chord is also the V chord in C Major and becomes the "pivot chord" to get back into the key of C Major. Because the modulation is so temporary, we don't usually perceive that we have gone to another key (even though we sort of did). The II Maj. Triad is frequently used in this manner as a secondary dominant and is notated as the V/V chord (read as "the five of five" chord - meaning the dominant chord of the dominant chord). That same II Major chord can also be "borrowed" out of a key's relative minor. If we go to the relative minor of C, we end up in A minor, which has a minor V chord in the natural minor - in this case the D minor triad. However, if we use the harmonic version of the scale this gives us a Major V triad (the notes D, F# and A). When a II major triad goes to the V chord it is being used as a secondary dominant. When it goes to a different chord it has been borrowed from another key, but in both cases it is notated as if it was a secondary dominant as in: I - VIm - V/V - V - I. As far as that goes, any chord in the scale can be approached by it's own secondary dominant: In C Major the A major triad would be the V/VI chord making a progression like: C - F - C - Em - E - Am - G - C possible, where E major is the secondary dominant of the Am (VIm) chord.

How do you change keys from B flat major to c major while playing smoothly on piano?
There are a number of ways, such as the following bridge format:1. From B-flat major, go into F major - this is pretty easy, since F is the dominant of B-flat.2. From F major, go into C major - which is also pretty easy to do since you are going from IV to I (where IV is F, and I is C).Harmonic progressions can be easily created by following what is known as The Circle of Fifths (see related links), which is a visual representation of the relationship between all of the 12 chromatic scales. In essence, you can smoothly go into the scale represented by the dominant or subdominant of your current scale.For example:- B-flat major can go to F major (the dominant) or to E-flat major (the subdominant - which is equal to a fifth below the tonic)- G minor can go to d minor (the dominant) or to c minor (the subdominant - which is equal to a fifth below the tonic)

Does term harmony refers to the horizontal aspect of music.?
That is an incredibly complex question. Let me outline a few things you need to know.Firstly, you must understand scales. For example, let's take the C Major scale because it's easy to work with. If you don't know, the C Major scale starts on C and has no sharps or flats, so it looks like this:... C - D - E - F - G - A - B - C ...Okay. Let's start with understanding harmony by looking at what are called triads.The C Major scale made up of 7 distinct notes (C through B) and 7 distinct triads. What are triads you ask? They are simply three note cords that are made by taking any note in a scale, skipping over the adjacent pitch to add the second note, and then skipping over the adjacent pitch again to add the third note of the triad. Here's what I mean:If we start on C, we will then skip over D to add E and then skip over F to add G. So a C Major Triad looks like this:... C - d - E - f - G - a - b - c ...So the C Major Triad consists of the pitches C, E, and G.Okay, so far so good. What if we start on G instead? Well, a triad in C Major that starts on G is going to give us the pitches G, B, D. Which for our information could be called a G Major Triad. What if we start on D? Then we get D, F, A. How about A? The we get A, C, E.I think you get the point. There is so much more for you to learn though! This doesn't even scratch the surface. We haven't talked about inversions, chord progressions, cadences, voice leading or and of the really cool stuff there is to learn. If you are at all interested in learning harmony, talk to a teacher of music. They will surely be able to give youOne last thing; as I have said before, a major scale consists of 7 triads. 3 of the triads are major, 3 of the triads are minor, and one of the triads is diminished. The triads that are built on the 1st, 4th, and 5th notes of a major scale are major triads. The triads that are built on the 2nd, 3rd, and 6th are minor triads. The triad that is built on the 7th triad is a diminished triad.Try playing around with these different chords and have fun!
What are the notes of all dominant scales?
There is actually no such thing as a "dominant scale", however you can use the notes of a dominant 7th chord as a scale and that can begin on any note, the dominant 7th chord in C major is G7 and G7 uses all white keys (G, B, D and F), the structure of a dominant 7th chord is the major triad plus the flatted 7th.
What is the difference between mager and miner notes?
first of all, learn how to spell. major* and secondly there isnt a difference. minor sounds like a major and a major sounds like a minor... and learn how to spell minor as well.
Why do you say that the right hemisphere is the subordinate or minor hemisphere?
It's not always the right hemisphare, the subordinate/minor hemisphere is the NOT dominant hemisphare. In more than 90% of population the left hemisphare is the dominant which makes the right the subordinate hemisphares. But in some (not all) left handed the right is the dominant hemisphere and the left is the subordinate hemisphare.
What are the different signatures and keys of music?
There are a total of fifteen keys in Western music. Keys come with two forms, sharp keys and flat keys and one comes with all naturals. The complete list of major keys are shown below: C major (or A minor) - no sharps/flats G major (E minor) - 1 sharp D major (B minor) - 2 sharps A major (F-sharp minor) - 3 sharps E major (C-sharp minor) - 4 sharps B major (G-sharp minor) - 5 sharps F-sharp major (D-sharp minor) - 6 sharps C-sharp major (A-sharp minor) - 7 sharps F major (D minor) - 1 flat B-flat major (G minor) - 2 flats E-flat major (C minor) - 3 flats A-flat major (F minor) - 4 flats D-flat major (B-flat minor) - 5 flats G-flat major (E-flat minor) - 6 flats C-flat major (A-flat minor) -7 flats There you go, those are all the different keys you can write in!
