Angle Relationships When Parallel Lines are Cut by a Transve

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

Define corresponding angles.

Back

Corresponding angles are the angles that are in the same position at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

Identify the angle relationship: Angle 1 and Angle 5.

Back

Corresponding angles.

Front

Identify the angle relationship: Angle 6 and Angle 7.

Back

Vertical angles.

Front

Identify the angle relationship: Angle 3 and Angle 8.

Back

Alternate interior angles.

Front

Identify the angle relationship: Angle 2 and Angle 7.

Back

Alternate exterior angles.

Front

What is the sum of the angles on a straight line?

Back

The sum of the angles on a straight line is 180 degrees.

Front

What is the sum of the angles around a point?

Back

The sum of the angles around a point is 360 degrees.
