Multiple Choice

What are the angles of a figure called?

• angle

• vertex

• arms

• corners

A special pair of angles

It is a pair of angles that have some kind of relationship between them

Special pair of angles

• 
  

  complementary - sum of angles are 90

• supplementary - sum of angles are 180

• adjacent angles - angles that are next to each other

• linear pair - 2 angles on a line /180

• angles on a straight line - more than 2 angles on a line /180

• vertically opposite angles -they are just opposite angles

LETS LEARN ABOUT IT SLIDE 1

Multiple Choice

What is complementary

• 90

• 180

Multiple Choice

What is supplementary

?

• 90

• 180

Multiple Choice

The measure of one angle is equal to its supplement . Find both the angles ?

• 45

• 90

• 180

• 3x

Multiple Choice

What is the complement of the angle - 45? (take time)

• x= 90-45

• x=180-45

• x=180-90

• 45=180-x

Multiple Choice

Find the supplement of 110?

• x=180-90

• x=180-110

• x=90-110

• x=110-90

ADJACENT ANGLES , LINEAR PAIR , VERTICALLY OPPOSITE ANGLES

LETS LEARN ABOUT IT - SLIDE 2 AND 3
