Transversals and Angle Pairs

Front

What are supplementary angles?

Back

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

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal. They are equal.

Front

What are alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines on opposite sides of a transversal. They are equal.

Front

If angle P measures 60 degrees, what is the measure of angle C if they are supplementary?

Back

Angle C measures 120 degrees.

Front

What is the measure of angle 3 if it is an alternate interior angle to angle 6, which measures 45 degrees?

Back

Angle 3 measures 45 degrees.

Front

What is the relationship between adjacent angles?

Back

Adjacent angles share a common side and a common vertex but do not overlap.

Front

What are complementary angles?

Back

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

Front

If angle 2 and angle 4 are supplementary, and angle 2 measures 75 degrees, what is the measure of angle 4?

Back

Angle 4 measures 105 degrees.

Front

What is the sum of the measures of angles on a straight line?

Back

The sum of the measures of angles on a straight line is 180 degrees.
