1. Consider a triangle ABC.2. Draw a line through vertex A, parallel to side BC.3. Angles formed at A are equal to angles B and C (alternate interior angles).4. The sum of angles at A is 180° (straight line).5. Therefore, ∠A + ∠B + ∠C = 180°.This proof demonstrates that the sum of interior angles in any triangle is indeed 180Maria Shaikh – Thank you very much for giving me such a nice answer 💗 – May 20, 2025 - 20:15
