Corresponding, Alternate Interior, Alternate Exterior Angles

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 lie between two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

The corresponding angles are equal.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

The alternate interior angles are equal.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate exterior angles?

Back

The alternate exterior angles are equal.

Front

Find the measure of the missing angle if one angle is 113 degrees.

Back

The missing angle is 67 degrees (180 - 113 = 67).

Front

Find the measure of the missing angle if one angle is 65 degrees.

Back

The missing angle is 115 degrees (180 - 65 = 115).

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 inside the parallel lines.
