What you'll learn

Each question helps you build key knowledge and skills.

  • 1A geometric proof should state the theorem or fact used at each step, not just the answer.
  • 2To prove triangles congruent, identify matching sides/angles and name the condition (SSS, SAS, ASA, RHS).
  • 3To prove triangles similar, show equal angles (AA) or matching side ratios.
  • 4Always finish a proof with a clear concluding statement.

Question mix
