Proving Triangles Congruent. Day 1. SWBAT: Use properties of congruent triangles. Prove triangles congruent by using the definition of congruence. 5. 6. The angle measures of a triangle are in the ratio of 5:6:7. Find the angle measures of the triangle. 7. Solve for m. Day 2 - Identifying Congruent Triangles.
Given: ∠ TQR ≅ ∠ RST ,QR TS Prove: ∆QRT ≅ ∆STR. 6. Given: DA ⊥ AB ,CB ⊥ AB ,DA ≅ CB , Reasons Introducing a new definition! Since we are proving two triangles congruent, then it follows that their corresponding parts are congruent. We typically abbreviate this in a proof using CPCTC which stands for: 7.
