200

What is the relationship between angles 3 and 6 ?

What are Alternate Interior Angles.

200
One way to prove that lines are parallel lines is through understanding that corresponding angles are
What is congruent
200

When two lines are cut by a transversal, the pair of angles on one side of the transversal and inside the two lines are called .... 

Consecutive Interior Angles

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

Linear Pair Angles

A pair of adjacent angles formed by intersecting lines. These angles are also supplementary.

300

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

What is 68. (same-side interior angles)

300
To prove that lines are parallel one must understand that same side interior angles are.
What is supplementary
300

If the measure of angle 1 = 4x-6 and the measure of angle 5 =122, what is the value of x?

What is 4x-6=122

4x=128 

x=32

400

Congruent angles formed by two intersecting lines. These angles are located across from each other.

What are vertical angles?

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

400


Angles 6 and 7 are vertical. 

If the measure of angle 6 is 75 and the measure of angle 7 is 3x, what is the value of angle 6 plus angle 7?

What is 50

3x=75 

x=25

500

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.

What are Alternate Interior Angles?

500

Consecutive Interior

 pair of angles on one side of the transversal and inside the two lines

500
