WebABC is an isosceles triangle with AB = AC and D is a point on BC such that AD ⊥ BC (Fig. 7.13). To prove that ∠BAD = ∠CAD, a student proceeded as follows:In ∆ ABD and ∆ ACD, AB = AC (Given) ,∠B = ∠C. 1-to-1 Tutoring ... What is the defect in the above arguments.[Hint: Recall how ∠B = ∠C is proved when AB = AC] Summary: ABC is ... WebSolution Construction: Draw a perpendicular from vertex A to line BC. BC = BD + DC ... [B - D - C] DC = BC - BD DC = 20 - 7 DC = 13 Ratio of areas of two triangles is equal to the ratio of the products of their bases and corresponding heights. ∴ A (∆ ABD) A (∆ ADC) AX BD AX DC A (∆ ABD) A (∆ ADC) = 1 2 × AX × BD 1 2 × AX × DC
