Question

In Δ ABC, ∠A = 30°, ∠B = 40° and ∠C = 110°. The angles of the triangle formed by joining the mid-points of the sides of this triangle are :

A. 70°, 70°, 40° 

B. 60°, 40°, 80° 

C. 30°, 40°, 110° 

D. 60°, 70°, 50°

Answer 1

Since, the triangle formed by joining the mid points of the triangle would be similar to it hence the angles would be equal to the outer triangle's angles.
