Name _____________________C-___Date______ Chapter 3 Angles and Triangles Practice Test/Study Guide Work with a partner to review during class. Each student must complete their own Practice Test for credit. Useful Vocabulary Parallel Lines Transversal Corresponding Angles Vertical Angles Interior Angles Exterior Angles Interior Angles of a Triangle Exterior Angles of a Triangle Perpendicular Lines Complimentary Angles Alternating Interior Angles Adjacent Angles Congruent Angles Supplementary Angles Alternating Exterior Angles Non-Adjacent Angles How Can You Know an Angle’s Measure? You can know the measure of an angle or determine its measure for these reasons. Angles are directly CONGRUENT (“geometry” for equal) because of these reasons: They are Corresponding Angles Vertical Angles Alternating Interior Angles Alternating Exterior Angles Angles measures may also be found because of the rules for the sum of: Supplementary Angles Interior Angles of a Triangle Exterior Angles of a Triangle Interior Angles of Polygons Exterior Angles of Polygons Chapter 3 Practice Test. Use the figure to find the measure of the angle. Explain your reasoning. Find the measures of the interior angles. Find the measure of the exterior angle. 50 3y (2y -10) Tell whether the triangles are similar. Explain/Prove It! Describe two ways you can find the measure of angle 5. 14. 15. 16. Use the given measurements to find the distance d across the pond.
