What is the sum of the interior angles of a quadrilateral?

• 90 degrees

• 180 degrees

• 360 degrees

• 500 degrees

What are complementary angles?

• Two angles whose sum is 90 degrees

• Two angles that are equal in measure

• Two angles whose sum is 180 degrees

• Two angles that are adjacent

How do you call ∠1 and ∠2 if m∠1= 150°and m∠2= 30°? Why?

• Supplementary angles, because the sum of the two angles is 180°.

• Complementary angles, because the sum of the two angles is 180°.

• Supplementary angles, because the difference of the two angles is 90°.

• Complementary angles, because the sum of the two angles is 90°.
