How do you prove a right angle

WebIt is possible to determine if a triangle contains a right angle using Pythagoras' theorem. If the squares of the two shorter sides add up to the square of the longest side, the triangle... 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)
