Angles from Transversal

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 alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie between two parallel lines on the same side of a transversal. They are supplementary, meaning they 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 angles.

Front

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

Back

The corresponding angles are equal.

Front

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

Back

The alternate interior angles are equal.

Front

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

Back

The alternate exterior angles are equal.

Front

If two parallel lines are cut by a transversal, what can be said about the same-side interior angles?

Back

The same-side interior angles are supplementary (they add up to 180 degrees).

Front

How do you identify corresponding angles in a diagram?

Back

Look for angles that are in the same relative position at each intersection of the transversal with the parallel lines.
