In a isosceles triangle abc with ab ac
WebGiven: ∆ABC is an isosceles triangle with AB = AC. Construction: Altitude AD from vertex A to the side BC. To Prove: ∠B = ∠C. Proof: We know, that the altitude of an isosceles triangle from the vertex is the perpendicular bisector of the third side. Thus, we can conclude that, ∠ADB = ∠ADC = 90º ----------- (1) BD = DC ---------- (2) WebIf ABC is an isosceles triangle with AB = AC and AP ⊥ BC, then ∠B = ∠C. ☛ Related Questions: ΔABC and ΔDBC are two isosceles triangles on the same base BC and vertices …
