• supplementary

• congruent

• complementary

• adjacent

Angles with the same measure

• vertical

• congruent

• complementary

• adjacent

The opposite congruent angles formed by intersecting lines, and share only a vertex

• vertical

• congruent

• complementary

• adjacent

Two angles that share a vertex and one side

• vertical

• congruent

• complementary

• adjacent

These two angles are (Choose 2)

• Adjacent Angles

• Vertical Angles

• Congruent Angles

• Supplementary Angles

• Complementary Angles

Solve. What is the $m\angle1=$  

•  $180\degree$  because it makes a straight line

•  $120\degree$  because $m\angle1+60\degree=180\degree$  

•  $60\degree$  , because they are congruent

• There is not enough information

These two angles are (Choose 2)

• Adjacent Angles

• Vertical Angles

• Congruent Angles

• Supplementary Angles

• Complementary Angles

Solve. What is the $m\angle?=$  

•  $33\degree$  because $m\angle?+57\degree=90\degree$  

•  $90\degree$   because it makes a right angle

•  $57\degree$  , because they are congruent

• There is not enough information

These two angles are (Choose 2)

• Adjacent Angles

• Vertical Angles

• Congruent Angles

• Supplementary Angles

• Complementary Angles
