Transversals

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are alternate interior angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are on the same side of the transversal and in corresponding positions.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that are on the same side of the transversal and inside the two lines.

Front

What are alternate exterior angles?

Back

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

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 corresponding angles?

Back

Corresponding angles are congruent.

Front

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

Back

Consecutive interior angles are supplementary (they add up to 180°).

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

Solve for x: If two parallel lines are cut by a transversal and one angle is 50°, what is the measure of the alternate interior angle?

Back

x = 50°.
