WebWhat if I solve this by saying that Triangle ABC is congruent to itself (through SAS) in this way - 1. AC congruent to AB (Symmetric Property) 2. Angle A congruent to Angle A (Reflexive) 3. Triangle ABC congruent to Triangle ABC (SAS) 4. So Angle B congruent to Angle C (CPCTC) Is this an acceptable way of proving it? • 2 comments ( 101 votes) WebArea of an Equilateral Triangle Formula.
