200

The measure of angle z

What is 105 degrees

300
When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.
What are Corresponding Angles.
300

Vertical Angles

A pair of vertical angles formed by intersecting lines. These angles are also congruent.

300

If the measure of angle 4 is 112, what is the measure of angle 6?

300

Find the measure of x.

What is x = 16o

3x + 132 = 180

3x = 48

x = 16o

300

An equation to represent this diagram.

y + z + x = 180

z + y + 60 = 180


400
What are vertical angles?
Congruent angles formed by two intersecting lines. These angles are located across from each other.
400
Alternate Exterior Angles
If two parallel lines are intersected by a transversal, these angles are located on the outside of the two parallel lines on opposite sides of the transversal.
400

What is the relationship between angles 5 and 8?

What are Vertical Angles.

400

If the measure of angle 2 is 30 degrees , what is the measure of angle 6?

What is 30 degrees.

400

Assuming this is a right angle, the measure of angle x.


What is 36o

500

What are Alternate Interior Angles?

When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.

500

Same-side interior angles 

If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.

500

If the measure of angle 2 is 37 degrees, what is the measure of angle 7? What is the angle relationship?

What is 37 and Alternate Exterior Angles.
