Identifying Angle Pairs

Front

What are vertical angles?

Back

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

What are corresponding angles?

Back

Corresponding angles are the angles that are in the same position at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

What are supplementary angles?

Back

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

What are alternate exterior angles?

Back

Alternate exterior angles are the pairs of angles that lie outside the two lines and on opposite sides of the transversal. They are equal when the lines are parallel.

What are same side interior angles?

Back

Same side interior angles are the pairs of angles that lie between the two lines and on the same side of the transversal. They are supplementary when the lines are parallel.

How do you identify corresponding angles?

Back

To identify corresponding angles, look for angles that are in the same relative position at each intersection of the transversal with the two lines.

How can you determine if two lines are parallel using alternate exterior angles?

Back

If the alternate exterior angles are equal, then the two lines are parallel.

What is the relationship between same side interior angles?

Back

Same side interior angles are supplementary, meaning their measures add up to 180 degrees.
