Because two of the triangles are identical, you can simply multiply the area of the first triangle by two: 2A1 = 2 (½bh) = 2 (½ab) = ab. The area of the third triangle is A2 = ½bh = ½c*c = ½c2. The total area of the trapezoid is A1 + A2 = ab + ½c2. 5.

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) WebJan 20, 2024 · Proof of Right Angle Triangle Theorem. 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)
