Transversal Angles

Front

What are vertical angles?

Back

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

Front

Identify the angle pair: \(\angle 13\) and \(\angle 14\).

Back

These angles are Same-Side Interior Angles.

Front

What are supplementary angles?

Back

Two angles whose sum equals 180° are called supplementary angles.

Front

Which angles are NOT supplementary?

Back

\(\angle 2\) and \(\angle 3\) are NOT supplementary angles.

Front

What is the relationship between corresponding angles?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles on opposite sides of the transversal but inside the two lines. They are equal if the lines are parallel.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles on opposite sides of the transversal but outside the two lines. They are equal if the lines are parallel.

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, and their measures add up to 180°.

Front

What are complementary angles?

Back

Two angles whose sum equals 90° are called complementary angles.

Front

How do you identify same-side interior angles?

Back

Same-side interior angles are on the same side of the transversal and inside the two lines. They are supplementary if the lines are parallel.
