Transversal angle pairs

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are always equal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are linear angles?

Back

Angles that are adjacent and form a straight line, adding up to 180 degrees.

Front

If ∠2 = 142°, what is the measure of its corresponding angle?

Back

142°.

Front

If ∠6 and ∠8 are vertical angles, what can we say about their measures?

Back

They are equal.

Front

Classify angles 3 and 7 if they are in the same position on different parallel lines cut by a transversal.

Back

Corresponding angles.

Front

If two angles are alternate interior angles, what can we conclude about the lines they are between?

Back

The lines are parallel.
