Unit 2 Lesson 1b:
Parallel Lines & Transversals

​Goal:

Students are going to be able to determine angle measures using properties of angles created by a transversal through parallel lines.

​Procedure:

1) Identify the angle type.
2) Use the properties of the angle (congruent or supplementary) to solve for the measures of unknown values, or missing angles.

What is the measure of angle B?

​

​Example 1:

What is the measure of angle F?

​

​Example 2:

Suppose angle 1 is equal to (2x - 5) and angle 3 is equal to 75*.

Solve for x.

​

​Example 3:

Suppose angle 5 is equal to (3x + 1) and angle 6 is equal to (5x-15).

Solve for x.
Find the measure of angle 6.
