Transversals

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.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines on opposite sides of the transversal and are equal in measure.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

How do you identify corresponding angles in a transversal?

Back

Corresponding angles can be identified by their position; they are located at the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the significance of alternate exterior angles?

Back

Alternate exterior angles are equal when two parallel lines are cut by a transversal, which helps in proving lines are parallel.

Front

What is the definition of a transversal?

Back

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

Front

How can you determine if two lines are parallel using angle relationships?

Back

If a pair of corresponding angles or alternate interior angles are equal, then the two lines are parallel.

Front

What are the properties of angles formed by a transversal?

Back

The properties include corresponding angles being equal, alternate interior angles being equal, and same-side interior angles being supplementary.

Front

What is the relationship between same-side interior angles?

Back

Same-side interior angles are angles that lie on the same side of the transversal and between the two lines; they are supplementary.

Front

What is the angle relationship when two parallel lines are cut by a transversal?

Back

When two parallel lines are cut by a transversal, corresponding angles are equal, alternate interior angles are equal, and same-side interior angles are supplementary.
