Angle Vocab Flashcard

Front

What is an adjacent angle?

Back

Adjacent angles are angles that share a common side and a common vertex.

Front

What are complementary angles?

Back

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

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 is the relationship between adjacent and complementary angles?

Back

Adjacent angles can be complementary if they share a side and their measures add up to 90 degrees.

Front

What is the relationship between adjacent and supplementary angles?

Back

Adjacent angles can be supplementary if they share a side and their measures add up to 180 degrees.

Front

Can two angles be both complementary and adjacent?

Back

Yes, two angles can be both complementary and adjacent if they share a side and their measures add up to 90 degrees.

Front

Can two angles be both supplementary and adjacent?

Back

Yes, two angles can be both supplementary and adjacent if they share a side and their measures add up to 180 degrees.

Front

What is an example of adjacent angles?

Back

Two angles that share a common ray and vertex, such as angle AOB and BOC.

Front

What is an example of complementary angles?

Back

Angle 30 degrees and angle 60 degrees are complementary because they add up to 90 degrees.
