How to Use Pythagorean Theorem

This is a right triangle.

We will find the ‘C’, or hypotenuse, of this right triangle, when only given ‘A’ and ‘B’.

A

B

C

So, in order to do this, we will use something called Pythagorean Theorem.

•Pythagorean Theorem uses the formula

A + 2

B2= C

2

This means that one leg of the triangle squared (or times itself) plus the other leg squared, equals the final leg, or the hypotenuse, squared.

Leg 1

Leg 2

23+ =?

2 = 42

23 = 9

4 + 9= 13

13 square rooted comes out as 3.5

So, 2

The third leg is 3.5
