Angle Relationships Review

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What is the relationship between Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines. They are equal when the lines are parallel.

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a transversal. They are equal when the lines are parallel.

Front

What are Supplementary Angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If angle 6 is 25 degrees, what is the measure of angle 7 if they are supplementary?

Back

Angle 7 is 155 degrees.

Front

What is the measure of angle 2 if it is supplementary to angle 3 which is 38 degrees?

Back

Angle 2 is 142 degrees.

Front

What is the relationship between angles 1 and 5 if they are Corresponding Angles?

Back

If angles 1 and 5 are corresponding angles, they are equal in measure when the lines are parallel.

Front

What is the Alternate Interior Angle to angle 3?

Back

The alternate interior angle to angle 3 is angle 5.

Front

What is the measure of angles that are Vertical Angles?

Back

Vertical angles are always equal in measure.

Front

How do you identify Corresponding Angles in a transversal?

Back

Corresponding angles can be identified as angles that occupy the same relative position at each intersection where a straight line crosses two others.
