Transversal Angle Relationships

Front

What are transversal angles?

Back

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

Front

What is a transversal?

Back

A transversal is a line that crosses at least two other lines.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are same-side interior angles?

Back

Same-side interior angles are angles that lie between two lines and on the same side of a transversal.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal; they are opposite angles formed by the intersection of two lines.

Front

If angle 1 = 27°, what is the measure of angle 4 if they are corresponding angles?

Back

Angle 4 = 27°.

Front

If angle 3 = 63°, what is the measure of angle 2 if they are alternate interior angles?

Back

Angle 2 = 63°.

Front

What is the sum of same-side interior angles when the lines are parallel?

Back

The sum of same-side interior angles is 180°.
