Complimentary Angles: Supplementary Angles: Vertical Angles: Adjacent Angles: Tell whether the following angles are complimentary, supplementary, or neither. 1. 2. 3. Two angles that add up to 90 degrees. The angles that are opposite one another when two lines intersect. Angles that share a common vertex and common side. Two angles that add up to 180 degrees. 1 2 4 3 9 12 11 10 7 8 6 5 Two adjacent supplementary angles are called a LINEAR PAIR!

Use the diagram to answer the following questions. Name two right angles. Name two acute angles. Name two obtuse angles. Name a pair of adjacent angles. Name a pair of complementary angles. 6. Name three pairs of supplementary angles. 4. Use the diagram. Tell how the angles are related and find missing angles measures. Find the value of x in the figure. Then find the unknown angle measures. 5. 6. 2x° 7x° 7x° (10x-21)° B A C F E D 1 2 4 3 5
