In any triangle - not just right angled ones - the following holds true.
* If angle A is opposite side a * and angle B is opposite side b * and angle C is opposite side c
then
* SinAº/a = SinBº/b = SinCº/c (this is known as The Sine Rule)
and
* a2 = b2 + c2 − 2bc cosA (This is known as The Cosine Rule)
So, all you ever need to know is three of the triangle's six properties and you can work out any of the others.
The formula of the hypotenuse (the longest side of the triangle) is the other two lengths squared and added together.

There is none because a triangle is a 2D shape -------------------------------------------------------------------------------- There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but not a volume.
yes. When you are finding the area of a triangle you do the same for all types of triangles.
You would have a difficult time finding a formula to prove that statement, for two main reasons: 1). The statement is false. A triangle is never a rhombus. 2). Formulas can describe things, but they can't 'prove' things.
The formula of the hypotenuse (the longest side of the triangle) is the other two lengths squared and added together.
The forumal for finding the finding the length of the hypotenuse of a right triangle is square root of a squared plus b squared equals c. The letters a and b are the two sides that the length is known and the c is the unknown side.
The side opposite the right triangle is the hypotenuse. The formula for finding the hypotenuse is A squared plus B squared equal C squared. C is the hypotenuse. If side A is 3 and side B is 4, the equation would read 9 plus 16 equal C squared, or 25 equals C squared. The square of 25 is 5, so the hypotenuse is 5.
Sin= Opposite leg/Hypotenuse Cos= Adjacent leg/ Hypotenuse Tan=Adjacent leg/ Opposite leg
by finding out the hypotenuse of the triangle
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
Pythagoras is most famous for discovering Pythagoras' Theorem, which is a formula for finding lengths of sides on a right angled triangle. The formula is: a2+b2= c2 where c is the hypotenuse (longest side of the triangle) and a and b are the shorter sides.
It is: sine = opposite/hypotenuse
The only triangle that has a hypotenuse is a right-triangle. The hypotenuse is the side opposite the right angle, so the angle is always 90 degrees. In this case, if you're just finding the angle then you don't need to know what the side lengths are.
The formula to finding the hypotenuse of a right triangle is not that difficult actually. The formula is as followes: A2 + B2 = C2 It is actuallt easier than it sounds. *Remember, the hypotenuse it the segmant of the triangle that is across from the right angle* Say the angles of the triangle are: 4, 5,and C (C= Hypotenuse you want to find) So, the two legs are A and B (it doesn't matter what order) and the hypotenuse is C A= 4, B= 5, C= What we want to find out. So plug them in: 42 + 52 = C2 42 is 4 * 4 which is 16 52 is 5 * 5 which is 25 C2 is what we are finding out 16 + 25 = C2 Add them now 16 + 25 = 412 So now you have to "unsquare" C2 (41) Which is: 6.40312424 (etc.) You can round to the nearest tenth of hundreth. So: 42 + 52 = 6.402 There you go!
the formula is 1side multiply by 3
