1. Dr. Fowler CCM1A EXAM REVIEW 01

2. Pythagorean Theorem leg hypotenuse The hypotenuse is always the longest side of a right triangle and is always opposite the right angle.

3. Using a 2 + b 2 = c 2  Looking for length of the hypotenuse  a 2 + b 2 = c 2  15 2 + 20 2 = c 2  225 + 400 = c 2  625 = c 2

4. Using a 2 + b 2 = c 2  Find the Leg  a 2 + b 2 = c 2  6 2 + b 2 = 10 2  36 + b 2 = 100  -36 -36  b 2 = 64  b = 8

5. Ex 1 Find the distance between the points P(-3, 2) and Q (-2, 4). Work inside parentheses Do powers before doing the addition!!!!!!
