In an isosceles triangle abc with ab ac 6
WebThe area of an isosceles triangle is given by the following formula: Area (A) = ½ × base (b) × height (h) The perimeter of the isosceles triangle is given by the formula: Perimeter (P) = 2a + base (b) Here, ‘a’ refers to the length of the equal sides of the isosceles triangle and ‘b’ refers to the length of the third unequal side. Solved Examples WebMar 28, 2024 · Transcript. Example 6 In an isosceles triangle ABC with AB = AC, D and E are points on BC such that BE = CD (see figure). Show that AD = AE. Given: ∆ ABC is isosceles, So, AB = AC Also, BE = CD To prove: AD = AE Proof: Since AB = AC Therefore, ∠ C = ∠ B In ∆ ACD and ∆ ABE, AC = AB ∠ C = ∠ B CD = BE So, ∆ ACD ≅ ∆ ABE ∴ AD = AE Hence proved

WebLet's draw an isosceles triangle with two equal sides as shown in the figure below. Given: ∆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 ... 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.
