This lesson has four missing angle puzzles that I created using a computer program so the puzzles are crisp and clean looking. I also included an answer key for all puzzles. Students must use basic geometric line and angle relationships to find the missing angles including vertical angles, linear pairs, alternate interior angles, alternate exterior angles, complementary angles, corresponding angles, triangle sum, quadrilateral sum ect. I also have a missing angle puzzle 2 and 3 if you would like
