WebWe know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal). But we already know angle ABD i.e. same as angle ABF = angle CBD which means angle BFC = angle CBD. WebAug 5, 2024 · In an isosceles triangle, ABC, AB = AC, and AD are perpendicular to BC. AD = 12 cm . The perimeter of ΔABC is 36 cm. Concept used: In the isosceles triangle, altitude and median are the same. Calculation: Since AD is perpendicular to BC, ΔADB is a right-angle triangle. We know the Pythagorean triplet, (13, 12, 5) So, AD = 12 cm, BD = 5 cm and ...

WebProperties of an Isosceles Triangle. Definition: A triangle is isosceles if two of its sides are equal. We want to prove the following properties of isosceles triangles. Theorem: Let ABC be an isosceles triangle with AB = AC. Let M denote the midpoint of BC (i.e., M is the point on BC for which MB = MC). Then. 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)
