Warm up

1. Solve 3x + 9 =-302. Simplify the expression 9x

+ 2y, where x = -5 and y = 2.

3. 8b + 3c – 4f , let b = -4, c= -3 and f = 6

4. Find the midpoint of the line segment containing the points (0, 7) and (4, 6).

5. I am a triangle with angle measures 23, 104 and 53 degrees, what am I?

Today’s Objective TSWBAT name and identify angle

relationships in order to solve for angle measurements.

EXAMPLE 1 Identify complements and supplements

In the figure, name a pair of complementary angles, a pair of supplementary angles, and a pair of adjacent angles.

EXAMPLE 2 Find measures of a complement and a supplement

a. Given that 1 is a complement of 2 and m 1 = 68°, find m 2.

EXAMPLE 3 Find angle measures

Sports

When viewed from the side, the frame of a ball-return net forms a pair of supplementary angles with the ground. Find m BCE and m ECD.

EXAMPLE 4 Identify angle pairs

Identify all of the linear pairs and all of the vertical angles in the figure at the right.

EXAMPLE 5 Find angle measures in a linear pair

Two angles form a linear pair. The measure of one angle is 5 times the measure of the other. Find the measure of each angle.
