Transversal Angles

Front

What are transversal angles?

Back

Transversal angles are angles formed when a transversal line intersects two or more lines.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal.

Front

What are vertical angles?

Back

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

Front

What does it mean for angles to be supplementary?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What does it mean for angles to be congruent?

Back

Congruent angles are angles that have the same measure.

Front

If angle 1 measures 40 degrees, what is the measure of angle 7 if they are corresponding angles?

Back

Angle 7 also measures 40 degrees.

Front

If angle 4 and angle 6 are alternate interior angles, what can we say about their measures?

Back

Angle 4 and angle 6 are equal in measure.

Front

What is the relationship between angle 3 and angle 7 if they are corresponding angles?

Back

Angle 3 and angle 7 have the same measure.
