Module 2 Topic C 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 relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

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

Front

If ∠A measures 150º, what is the measure of the angle that is supplementary to ∠A?

Back

The measure of the angle that is supplementary to ∠A is 30º.

Front

What is the sum of the measures of angles in a triangle?

Back

The sum of the measures of angles in a triangle is always 180º.

Front

What are 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

If ∠a + ∠b = ∠d, what can be said about angles ∠a and ∠b?

Back

Angles ∠a and ∠b are complementary to angle ∠d.

Front

What is the measure of an angle that is complementary to a 45º angle?

Back

The measure of the angle that is complementary to a 45º angle is 45º.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180º.

Front

If two angles are vertical angles, what can be said about their measures?

Back

Vertical angles are always equal in measure.

Front

What is the measure of ∠3 if it is given that ∠3 is 45º?

Back

The measure of ∠3 is 45º.
