Warm Up

Simplify each expression.

1.90 –(x + 20)

2. 180 – (3x – 10)

Write an algebraic expression for each of the following.

3. 4 more than twice a number

4. 6 less than half a number

slide4

Name:

  • Adjacent ∠’s
  • 2. Linear pairs
  • 3. Vertical ∠’s
supplementary angles
Supplementary Angles
  • Angles that add up to 180 degrees.
complementary angles
Complementary Angles
  • Angles that add up to 90 degrees.
slide8

Find the measure of each of the following.

A. complement of F

B. supplement of G

slide9

Find the measure of each of the following.

a. complement of E

b. supplement of F

find the measure of each angle
FIND the MEASURE of each angle.

1. ∠ SOT

2. ∠ POU

3. ∠ ROS

4. ∠ POR

5. ∠ SOU

6. ∠ TOU

7. ∠ POS

8. ∠ UOQ

slide17

A. Name 2 pairs of vertical angles.

  • B. If ray BF bisects ∠ABC, what two angles must be equal.
  • C. Classify each as acute, obtuse, right or straight.
    • 1. ∠BAF
    • 2. ∠FCE
    • 3. ∠BFA
slide18

An angle is 10° more than 3 times the measure of its complement. Find the measure of the complement.

slide19

An angle’s measure is 12° more than the measure of its supplement. Find the measure of the angle.

Lesson Quiz: Part I

  • mA= 64.1°, and mB=(4x – 30)°. Find the measure of each of the following.
  • supplement of A
  • 2. complement of B
  • 3. Determine whether this statement is true or false. If false, explain why. If two angles are complementary and congruent, then the measure of each is 90°.
slide21

mXYZ = 2x° and mPQR = (8x - 20)°.

4. If XYZ and PQR are supplementary, find the measure of each angle.

5. If XYZ and PQR are complementary, find the measure of each angle.
