Proofs concerning isoceles triangles angles
WebBy the isosceles triangle theorem, we have 47^\circ=\angle ABC=\angle ACB 47∘ = ∠ABC = ∠AC B. Since the angles in a triangle sum up to 180^\circ 180∘, we have. In triangle ABC ABC shown above, AD=DF AD = DF and … WebBut the angle FBC was also proved equal to the angle GCB, and they are under the base. Therefore in isosceles triangles the angles at the base equal one another, and, if the equal straight lines are produced further, then the angles …
