Angles Formed by a Transversal

Front

What is a transversal in geometry?

Back

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

Front

Define corresponding angles.

Back

Corresponding angles are pairs of angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What are alternate exterior angles?

Back

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

Front

Define same-side interior angles.

Back

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

Front

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

Back

Corresponding angles are equal.

Front

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

Back

Alternate interior angles are equal.

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 (add up to 180 degrees).

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

Alternate exterior angles are equal.
