Angle Relationships

Which of the following is NOT an example of supplementary angles?

•  $\angle7\ and\ \angle8$  

•  $\angle2\ and\ \angle3$  

•  $\angle1\ and\ \angle7$  

•  $\angle6\ and\ \angle4$  

∠1 and ∠3 can best be described as -

• complementary angles
• supplementary angles
• vertical angles
• adjacent angles

What are supplementary angles?

• Angles that add up to 180°
• Angles that add up to 90°
• Angles that are equal to each other
• Angles that are opposite of each other when lines intersect
