Q2 of 95 Page 15

In a triangle ∠ABC, ∠A =50°, ∠B =60° and ∠C = 70°. Find the measure of the angles of the triangle formed by joining the mid-points of the sides of this triangle.

Given,


In a ΔABC


∠A =50°


∠B =60°


∠C = 70°


Let DEF are mid point of ΔABC


BDEF and CDFE are parallelogram


∠B = ∠E & ∠C = ∠F


∠E = 60°


∠F = 70°



Similarly


∠D = ∠A


∠D = 50°
