Types of Angles

Front

What is an adjacent angle?

Back

Angles that share a common side and vertex, and do not overlap.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

Angles that are opposite of each other when two lines intersect.

Front

If angle A is 30 degrees, what is the measure of its complementary angle?

Back

60 degrees.

Front

If angle B is 120 degrees, what is the measure of its supplementary angle?

Front

What is the sum of the measures of two complementary angles?

Back

90 degrees.

Front

What is the sum of the measures of two supplementary angles?

Back

180 degrees.

Front

Can two angles be both complementary and supplementary?

Back

No, they cannot be both; complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees.

Front

What is an example of adjacent angles in a real-life scenario?

Back
