WebAlso, AB = AC since the triangle is isosceles. Thus, triangle BAD is congruent to CAD by SAS (side-angle-side). This means that triangle BAD = triangle CAD, and corresponding sides and angles are equal, namely: … WebSince it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem. For the same reason, if m∠B < m∠C, then AC < AB. This is a contradiction to what is given. fir militaryWebIf in an isosceles triangle ABC, with AB = AC, and the bisectors of ∠B and ∠C intersect each other at O, we have proved that OB = OC and AO is the angle bisector ∠A. ☛ … eukaryotic multicellular heterotroph
