Angle Pair Relationships Flashcard

Front

What are angles that add up to 180° called?

Back

Supplementary Angles

Front

What is the relationship between two angles that share a common vertex and a common side but do not overlap?

Back

Adjacent Angles

Front

What do you call a pair of angles that are opposite each other when two lines intersect?

Back

Vertical Angles

Front

What is the measure of the missing angle if one angle is 39°?

Back

141° (since 180° - 39° = 141°)

Front

If two angles form a linear pair, what is true about their measures?

Back

They are supplementary, meaning they add up to 180°.

Front

What is the best way to describe angles that are formed when two lines intersect?

Back

Vertical Angles

Front

If two angles are complementary, what is the sum of their measures?

Back

90°

Front

What is the term for angles that are in the same position on parallel lines when crossed by a transversal?

Back

Corresponding Angles

Front

If angle A measures 70°, what is the measure of its supplementary angle?

Back

110° (since 180° - 70° = 110°)
