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)

Theorem:In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle. To prove: ∠B = 90°. Proof: We have a Δ ABC in which AC2 = AB2 + BC2. Also, read: c2 = a2 + b2. c = √ (a2 + b2) WebMar 9, 2015 · Here Δ A B C is the right-angled triangle and R is the midpoint of M N.
