It’s July! Since it is half a year already, let us look back about what proofs we have learned so far.

For the past year, we have learned the proofs of 7 mathematical theorems, 3 in Geometry and 4 in Algebra. There are also three worked out proofs in triangle congruence. Congruence theorems like SAS, SSS, and ASA are used in these proofs.

Year in Review – 1st Semester

• Absolute Value Proofs: Products and Quotients
• Proof of the Converse of the Pythagorean Theorem
• Proof that The Diagonals of a Rhombus are Perpendicular
• A Proof of The Trapezoid Angle Theorem
• The Proof of the Kite Symmetry Theorem
• Sample Proof on Triangle Congruence Part 1
• Sample Proof on Triangle Congruence Part 2
• Sample Proof on Triangle Congruence Part 3
• Slope of Perpendicular Lines Theorem
• The Sum and Product of Roots Theorem
