Find the area of ΔAOB. Solution: Given: A triangle AOB, with ∠AOB = 90 o, AC = BC, OA = 12 cm and OC = 6.5 cm As we know, the midpoint of the hypotenuse of a right triangle is equidistant from the vertices.

WebTriangles ΔAOD and ΔBOC are similar by AAS congruency since: (i) ∠A = ∠B (They are perpendiculars) (ii) AD = BC (As given in the question) (iii) ∠AOD = ∠BOC (They are vertically opposite angles) ∴ ΔAOD ≅ ΔBOC. So, AO = OB (by the rule of CPCT). Thus, CD bisects AB (Hence proved). 1 WebApr 10, 2024 · Les triangles.
