Transversals Flashcard

Front

What is a complementary angle?

Back

An angle that, when added to another angle, results in a sum of 90 degrees.

Front

What is a supplementary angle?

Back

An angle that, when added to another angle, results in a sum of 180 degrees.

Front

If Angle A measures 75 degrees, what is the measure of its complementary angle?

Back

15 degrees.

Front

If Angle A is 21 degrees and is complementary to Angle B, what is the measure of Angle B?

Back

69 degrees.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What is a linear pair of angles?

Back

Two adjacent angles that form a straight line and sum up to 180 degrees.

Front

If two angles are supplementary and one measures 101 degrees, what is the measure of the other angle?

Back

79 degrees.

Front

What is the sum of the measures of complementary angles?

Back

90 degrees.
