MAFS.912.G-CO.3.9:  Prove theorems about lines and angles; use theorems about lines and angles to solve problems. (Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment’s endpoints.)

Learning Targets and Learning Criteria
  • Students will be able to use algebra to find angle measures using their knowledge of complementary and supplementary angles as well as vertical angles and linear pair angles
  • Students will understand how to prove that vertical angles are always congruent
  • Students will demonstrate their knowledge of basic geometry and angle vocabulary
  • Students will know how to name points, lines, and planes
Classroom Activities


  • We will review angle relationships and practice solving equations to find angle measures
  • Students will copy notes on page 4 of ISN on “Proving Vertical Angles Congruent”
  • Students will play Angle Relationship Bingo


  • Continue Angle Relationship Bingo
