Angle Relationships

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect. They are always congruent.

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are congruent.

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What does it mean for angles to be Supplementary?

Back

Two angles that add up to 180 degrees.

Front

If two angles are Corresponding Angles, what can be said about their measures?

Back

They are equal in measure.

Front

How can you identify Alternate Interior Angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and between the two lines.

Front

What is the relationship between Alternate Exterior Angles?

Back

They are equal in measure when the lines are parallel.

Front

What is the sum of the measures of Vertical Angles?

Back

Vertical angles are always equal, so their measures are the same.

Front

If two lines are cut by a transversal, what can be said about the Corresponding Angles?

Back

If the lines are parallel, the corresponding angles are congruent.
