Question

In a triangle $\angle$ABC, $\angle$A = 50${}^o$, $\angle$ = 60${}^o$ and $\angle$C = 70${}^o$. Find the measures of the angles of the triangle formed by joining the mid- points of the sides of this triangle.

• A. 50${}^o$, 60${}^o$, 70${}^o$
• B. 60${}^o$, 70${}^o$, 70${}^o$
• C. 50${}^o$, 50${}^o$, 80${}^o$
• D. none of the above

Answer 1

The correct option is A 50${}^o$, 60${}^o$, 70${}^o$

Angles formed by the triangle joining the mid points of the sides of given triangle are same as the original triangle
