Transversal Angle Relationships

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

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 parallel lines. They are supplementary, meaning their measures add up to 180 degrees.

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points, creating various angle relationships.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

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 parallel lines. They are equal in measure.

Front

What does it mean for angles to be supplementary?

Back

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

Front

What does it mean for angles to be complementary?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the significance of angle relationships in geometry?

Back

Angle relationships help in solving problems involving parallel lines and transversals, allowing for the calculation of unknown angle measures.

Front

How can you identify corresponding angles in a diagram?

Back

Corresponding angles can be identified by locating angles that are in the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the relationship between vertical angles?

Back

Vertical angles are pairs of angles that are opposite each other when two lines intersect. They are equal in measure.
