Chapter 2 Lines and Angles Review

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

What is the measure of vertical angles?

Back

Vertical angles are always equal.

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

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

Back

The corresponding angles are equal.

Front

What are alternate interior angles?

Back

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

Front

If angle 2 is 70 degrees, what is the measure of angle 3 if lines are parallel?

Back

Angle 3 is 110 degrees.

Front

What is the relationship between alternate exterior angles when two lines are parallel?

Back

Alternate exterior angles are equal.

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 relationship between the angles formed by two intersecting lines?

Back

The angles formed by two intersecting lines are vertical angles and are equal.

Front

What is the measure of angle 8 if angle 7 is 8 degrees?

Back

Angle 8 is 8 degrees.
