Transversals

Front

What is a transversal in geometry?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

What are alternate exterior angles?

Back

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

How do you find the measure of an angle when given its supplementary angle?

Back

To find the measure of an angle when given its supplementary angle, subtract the measure of the supplementary angle from 180°.

What is the equation to find the value of x in angle relationships?

Back

The equation will depend on the specific angle relationships, but it often involves setting up an equation based on the relationships (e.g., x + y = 180° for supplementary angles).

What are the properties of parallel lines cut by a transversal?

Back

When parallel lines are cut by a transversal, corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.
