1. 1.6 Describing Pairs of Angles
Learning Goals:
Students will identify complementary and supplementary angles, vertical angles, and linear pairs and use those identities to find congruent angles, values of x and apply the ans, and missing degrees of other angles.

4. Name an angle pair that satisfies each condition.
a. two acute vertical angles
b. two adjacent angles whose sum is less than 90
Example 5-1c

5. ALGEBRA Find the measures of two supplementary angles if the measure of one angle is 6 less than five times the other angle.
Example 5-2a

6. Perpendicular Lines that form right angles are perpendicular.
Perpendicular lines intersect to form four right angles and form congruent adjacent angles.
Segments & rays can be perpendicular to lines or to other line segments & rays.
The right angle symbol indicates that the lines are perpendicular.

7. ALGEBRA Find x so that .
Example 5-3a
