alternate angles, transversal

Front

What are alternate interior angles?

Back

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

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

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

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal in measure and are formed by two intersecting 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.

Front

What is the sum of angles on a straight line?

Back

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

Front

If angle 1 is 70 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle is also 70 degrees.

Front

If angle 3 is 110 degrees, what is the measure of angle 4 if they are vertical angles?

Back

Angle 4 is also 110 degrees.
