1. Warmups Find three consecutive integers whose sum is 96.

2. 3-4 Angles and Triangles Objective: To find the complement and supplement of an angle

3. Complement Complement: 2 angles whose sum is 90 o Remember, sum means adding (+) 1 2

4. Examples Find the complement of each angle: 1) 50 o 1 st angle = 50 o 2 nd angle = c 50 + c = 90 -50 c = 40 o 2) 30°

5. Examples (do with me) 3) (2x) o 4)48 o

6. TOO (with a partner): Find the complement of each angle: 1) 130º2) (x + 6)º Answers: 1) NONE 2) (84 – x)º If the answer is negative, then there is “none!”

7. Supplement Supplement: 2 angles whose sum is 180 o 180 o

8. Examples (do with me): Find the supplement of each angle: 1) 130 o 2) (x-20)° 1 st angle = 130 o 2 nd angle = s 130 o + s = 180 o -130 s = 50 o

9. TOO (with a partner): Find the supplement of each angle: 1) 90º2) (4x + 38)º Answers: 1) 90º 2) (142 – 4x)º
