pythag thrm

a^2 + b^2 = c^2

apoorvk · Answer

where c is the largest side, opposite to the right angle, and is called hypotenuse

Pythagorean Theorem

The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

If you are given 3 and 4 as the legs of a right triangle and want to find the length of the hypotenuse, then use the Pythagorean Theorem.

h^2 = 3^2 + 4^2
h^2 = 9 + 16
h^2 = 25
h = 5

Note: -5 is another solution to h^2 = 25 but -5 cannot be the length of a side of a triangle.
