Naming Angles and Relationships

What type of angle is shown?

• acute

• obtuse

• right

• straight

The angle relationship shown is -

• complementary angles

• supplementary angles

• vertical angles

• angle bisector

The angle relationship shown is - 

• complementary angles

• supplementary angles

• vertical angles

• adjacent angles

Identify the relationship:

• vertical angles

• supplementary

• linear pair

• adjacent angles

Identify the relationship:

• vertical anlges

• linear pair

• complementary angles

• right angles

Angles A and B are an example of a linear pair. This means...

• they add up to 90^o

• they are congruent

• they add up to 180^o

The angle shown here is

• = to 90^o

• = to 180^o

• an unknown measure
