Unit D Test

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

Identify supplementary angles.

Back

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

Front

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

Back

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

Front

What is the measure of angle STQ if m<UTQ = 134 and PR || SU?

Back

m<STQ = 46 degrees.

Front

If m<TSQ = 46 and RT || UW, what is m<WVS?

Back

m<WVS = 46 degrees.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

Define complementary angles.

Back

Complementary angles are two angles whose measures add up to 90 degrees.

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 angle UWV measures 72 degrees, what is the measure of its complement?

Back

The complement of angle UWV is 18 degrees.

Front

What is the definition of a transversal?

Back

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