Angle Relationships
Vertical angles only touch at the vertex- they are EQUAL
Supplementary angles share one side and make a striaght line. They add up to 180.
Complementary angles form a right angle (see the little box). They add up to 90.
3
Supplementary Angles
The two angles form a straight line so we know they are supplementary (and add up to 180).
We will write an equation 79 + x = 180
Solve the equation by subtracting 79 from both sides
x = 101

Complementary Angles
The two angles form a right angle so we know they are complementary (and add up to 90).
We will write an equation 73 + x = 90
Solve the equation by subtracting 73 from both sides
x = 17
