The Pythagorean Theorem A tool for right triangle problems only

When do I need to use the Pythagorean Theorem ? When I know: length of 2 sides And Need to know: length of 3rd side

What is the Pythagorean Theorem? b c

The hypotenuse is ALWAYS across the right angle. a & b are the legs and c is the hypotenuse a b c

Using a2 + b2 = c2 5 7 x

Using a2 + b2 = c2 15 20 x

Using a2 + b2 = c2 Round x to the Nearest whole number 6.2 12.3 x

Using a2 + b2 = c2 6 x 10

Using a2 + b2 = c2 Round x to the Nearest whole number 3.1 x 5.7

Using a2 + b2 = c2 24 x 25
