The Pythagorean theorem is used to find the length of the missing side in a right triangle.

4
Important facts Pythagorean theorem can only be used in right triangles Legs are always the sides adjacent to the 90 degree angle (next to) It does not matter which leg is a or b Hypotenuse is always the longest leg called c.

5
What is a right triange? A right triangle is a triangle with 90 degree angle.

6
Formula a and b represent the legs c represents the hypotenuse

7
How formula works… Determine legs and the Hypotenuse hypotenuse leg
Right angle

8
Steps 1. Find legs and hypotenuse 2. Square the legs (a,b)
3. Add legs together 4. Square root the answer 5. Answer is the length of the hypotenuse [c]

9
Square both legs and add
= c2 = c2

10
Square root answer (hypotenuse)
= 25 = 52

11
All together

12
Proof

13
Example problem Finding a leg

14
Example 2 Find the hypotenuse
