How do you find a right isosceles triangles side using angle measures?

Answer 1

You use the Formula A(2) +B(2) = C(2)
C is the hypotenuse. The hypotenuse is the largest side which is always opposite of the right angle. A and B are sides of and it does not matter what side you use as a or b

For Example: the sides are 5 12 and 6.


|\
5| \ 12
|__\
6

a b c
5(5) + 6(6) = 12(12) = 144
25 36 61

Since 144 does not equal 61 it is NOT a right triangle. If they were equal the triangle would be a right triangle.

|\
4| \ 5
|__\
3

a b c
3(3) + 4(4) = 5(5) = 25
9 16 25

Since 25 Equals 25 The Triangle IS a Right Triangle.

If it gives you Angle The Hypotenuse (C) and one side(A) The Equation would look like this:

C(2) - A(2) = B(2)

5(5) - 3(3) = 4(4)
25 - 9 = 16




Hope It Helped; and sorry for all that to read!
