Special Angles: Transversals

Front

What are special angles formed when a transversal crosses two parallel lines?

Back

Special angles include corresponding angles, alternate interior angles, alternate exterior angles, and same-side interior angles.

Front

Define corresponding angles.

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to the transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between the two parallel lines but on opposite sides of the transversal.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines but on opposite sides of the transversal.

Front

Define same-side interior angles.

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

Corresponding angles are congruent.

Front

If two parallel lines are cut by a transversal, what can be said about alternate interior angles?

Back

Alternate interior angles are congruent.

Front

If two parallel lines are cut by a transversal, what can be said about alternate exterior angles?

Back

Alternate exterior angles are congruent.

Front

If two parallel lines are cut by a transversal, what can be said about same-side interior angles?

Back

Same-side interior angles are supplementary (they add up to 180 degrees).

Front

What is the measure of angle B if angle W is 50 degrees and they are corresponding angles?

Back

Angle B is also 50 degrees.
