Angle relationship Flashcard

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What are vertical angles?

Back

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

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What is the relationship between complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What is the relationship between supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

If Angle A and Angle B are complementary and Angle A is 35 degrees, what is Angle B?

Back

Angle B = 55 degrees.

Front

If Angle C and Angle D are supplementary and Angle C is 70 degrees, what is Angle D?

Back

Angle D = 110 degrees.
