Flashcardizz G-3.2A: Angles and Intersecting Lines

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 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 are vertical angles?

Back

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

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.

Front

How do you identify alternate interior angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and between the two parallel lines.

Front

How do you identify alternate exterior angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and outside the two parallel lines.
