Angles Review

Basic Angles

Geometry: Basic Angle Relationships

7th Grade Angles

• Complementary

• Supplementary

• Vertical

• Adjacent

• Triangle Angles (next presentation)

Like complementary angles, two angles do not have to be connected to be considered supplementary.

Complementary Vs Supplementary

• C is before S

• 90 is before 180

• So, C goes with 90 & S goes with 180

Vertical angles are on opposite sides of the vertex 
from each other and do not share any sides.

Finding a Variable

Sometimes we need to find a value within an angle and not the full angle measurement. We would still set up an equation to do this.
