Catete are those sides of a right triangle that form the right angle in it. In turn, opposite to their side is the hypotenuse.
There are several ways to calculate leg length.
1) Get out of the basic trigonometricfunctions. Given a right-angled triangle, whose c - the hypotenuse, a, and b - legs are, eh? and? - Sharp edges. Then to calculate the length of the legs you can use the following equations: a = c * cos?
a = c * sin?
a = b * tg?
b = c * cos?
b = c * sin?
b = a * tg?
2) follows from the properties of similar triangles. Let a rectangular ABC triangle, where AB - the hypotenuse (c), BC and AC - catheti (a and b, respectively), CD - height drawn from vertex C to the hypotenuse AB (hc), AD and DB - segments obtained by dividing hypotenuse height (bc and ac, respectively). Then, to calculate the length of the legs a and b, you can use the following equations:
a = v (ac * c)
b = v (bc * c).
