# A composition of reflections across two parallel lines is a?

translation

### Skew lines and parallel lines exactly the same?

Skew lines are not parallel. Parallel lines are across from each other in some way and are exactly parallel.

### How do you translate a triangle?

Within a euclidian plane R2, an isometry f is a translation if it f(x,y) = (x+a,y+b) for all points (x,y) in R2. It can also be constructed as the composition of two reflections in parallel lines.

### Is glide reflection equivalent to two reflections across two vertical lines?

No. Glide reflection is a combination of an ordinary reflection and a slide along the line of reflection. A two reflections across two vertical lines is a translation without any reflection or rotation.

### What parallel lines means?

Parallel lines are staright across from each other. = Equal signs are parallel from each other. So are railroad tracks. The lines in the following letters are parallel: E Z N The lines in the "E" are parallel. The top and bottom lines in "Z" are parallel. The left and right lines in an "N" are parallel.

### Incisions should be made across rather than parallel to cleavage lines produced by collagen fiber bundles?

NO CLEAVAGE LINES SHOULD BE MADE PARALLEL. When and incision is made parallel to the cleavage lines, the skin gapes less and heals more readily than when the incision is made across the cleavage lines

### Draw parallel horizontal lines?

Parallel lines are lines that, if extended, would never intersect with eachother. This means that they are going in the same direction, eg. | |, but not | \. Horizontal means that that are going across, eg. ___________________, not |. An example of a lines that are parallel and horizontal: _____________________________________ _____________________________________

### What are the Lines that runs across from east to west are called lines of what?

They are lines of latitude, and run parallel to the Equator.

the importance lines on longitude's, is parallel line in the across the equation

### What shape has perpendicular and parallel lines?

A square and a rectangle have perpendicular and parallel lines. The two side lines extending upwards from the base line are perpendicular to the base line. The line extending from each of the side lines across the top is perpendicular to the side lines. The top line is also parallel to the base line, and the side lines are also parallel to each other.

### How can you determine if two lines are parallel or perpendicular?

If the two lines are parallel, they will never connect. A straight line drawn across those lines will intersect them at identical angles. If you have perpendicular lines, they intersect and all four angles that they make are 90 degrees.

### What is meant by series and parallel circuits?

series circuits mean one thing after another ,in series. parallel means two parallel lines that the components go across.

### How are trapizoids and rectangles the same?

they both have at least one pair of parallel sides and they both are not regular polygons. Parallel lines are two lines that are across from each other and do not cross like a = sign

### Another term for lines of latitude?

Parallels. An easy way to remember this is by remembering that lines of lattitude run parallel across the earth.

### What is the fine in NJ for crossing the yellow diagonal lines while making a left turn?

It is not illegal, in any state, to turn left (or in fact, U turn) across single parallel yellow lines--however, crossing double parallel yellow lines is an infraction.

### What is projection has parallel latitude lines and parallel longitude lines?

A Mercator projection has parallel latitude lines and parallel longitude lines.

### How do you describe parallel?

Two lines on a graph that are parallel have the same slope and they will never meet. Two objects (such as two pencils) that are parallel are at the same angle. Two sides of a shape that are parallel are across from each other and at the same angle.

### Is a rhombus and a parallel the same?

No, because a rhombus is a shape and a parallel is not a shape it is a term for two lines that go across an object and the two lines never make contact with each other, once again it is not a shape. So no they are not the same.

### Does perpendicular have parallel lines?

= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.

### Is there a parallelogram with only one right angle?

No, because all lines need to be parallel from the one they're across.

### Are parallel lines actually parallel?

If they were not actually parallel then they would not be parallel lines!

### What is the function of parallel lines?

parallel lines are diagonal lines or increasing lines

### How many pairs of parallel lines does a triangle have?

There cannot be parallel lines in any [plane] triangles.

### Which shape has parallel lines but no perpendicular lines?

A rhombus has parallel lines but no perpendicular lines.

### Real examples for parallel lines?

railway tracks, an equals sign ( = ) or the ribs on a central heating radiator. A single line can't be parallel, unless there's another line present. The edges of the question box across from each other. | | | | Yes, the two letters 'el' in the word 'parallel'. Also, a pair of railroad tracks. Parallel lines never travel alone. It is very likely to have the thing you are looking at (the screen)… Read More

### Can parallel lines be intersecting lines?

No, parallel lines do not intersect, and never will.

### These are lines parallel to the equator?

Lines parallel to the equator are lines of latitude.

### H many parallel lines in F and W?

Two parallel lines, so one pair of parallel lines. Which are the two horizontal lines in F. Parallel lines just have the same slope, so they will never touch. So l l are parallel lines.

### Why aren't skew lines parallel?

Because of the way parallel lines are defined. Parallel lines never meet, but to qualify as parallel lines, additional conditions may apply. From Wikipedia: "Two lines in a plane that do not intersect or meet are called parallel lines." Emphasis added.

### What is meaning of parallel?

Parallel means exactly across from. These two lines that form an equals sign are parallel: =. Some more examples of parallel items are railroad tracks, all the sides of a square (the left and right are parallel from each other, and the top and bottom are parallel from each other). Hope this helps! : ]

### Do parallel lines meet at a 30 dregrese angle?

Lines that meet are not parallel, and parallel lines never meet.

### What are lines that run parallel from the equator called?

There are no parallel lines that run FROM the equator. Lines that are parallel TO the equator are the latitudes.

### Are they intersecting lines are never parallel?

are intersecting lines never parallel YES intersecting lines do not have the ability to be parallel

### Are intersecting lines also parallel?

Parallel lines cannot intersect in the Euclidean plane. Intersecting lines are not parallel.

### What is Perpendicular and Parallel?

Perpendicular is when two lines cross... Parallel is when two lines never meet.... _____________ _____________ = PARALLEL LINES If they cross they are perpendicular, if they don't, they are parallel.

### What are 3 characteristics of parallel lines?

Not sure if these are the ones that you are looking for, but here are three: Parallel lines do not intersect. Parallel lines lie in the same plane. parallel lines have the same slope.

### Has parallel lines of latitude and longitude?

Lines of latitude are parallel; lines of longitude are not.

### What are some examples of parallel lines and a pair of perpendicular lines?

Railroad tracks or the number 11 are parallel lines. A cross or a small t are perpendicular lines. Also the two ll's in the middle of parallel are parallel lines.

### What is a good sentence for parallel lines?

eHow Education Math Education Number Lines What Are Parallel Lines? What Are Parallel Lines? The white lines are parallel. Parallel lines are one of the most basic ideas in geometry. Most people learn about parallel lines early in their education, even in subjects other than math such as art. Despite being a very simple concept, most parallel lines we see in nature are man-made.

### Where are the parallel sides of a polygon?

The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.

### Parallel lines can be perpendicular?

It is impossible for parallel lines to be perpendicular. Perpendicular lines are intersecting lines, meaning that they cross each other. Parallel lines, on the other hand, are lines that never meet, no matter how far they are extended in either direction. So intersecting lines (which includes perpendicular lines) and parallel lines are exact opposites. Parallel lines will never meet or cross; they cannot be perpendicular.

### What is parallel line segment?

lines which lie in same pane are known as parallel lines or lines which do not intersect are known as parallel lines they extend in both the direction

### What shapes have perpendicular lines and no parallel lines?

Right triangles have a set of perpendicular lines and no parallel lines.

### Are parallel lines also called skew lines?

No. Skew lines are lines in different planes that are parallel.
