WebProof: In a triangle ABC, base angles are equal and we need to prove that AC = BC or ∆ABC is an isosceles triangle. Construct a bisector CD which meets the side AB at right angles. Now in ∆ACD and ∆BCD we have, ∠ACD = ∠BCD (By construction) CD = CD (Common side) ∠ADC = ∠BDC = 90° (By construction) Thus, ∆ACD ≅ ∆BCD (By ASA congruence criterion) WebTo prove the AAS congruence rule, let us consider the two triangles above ∆ABC and ∆DEF. We know that AB = DE, ∠B =∠E, and ∠C =∠F. We also saw if two angles of two triangles are equal then the third angle of both the triangle is equal since the sum of angles is a constant of 180°.
