Chapter 3, Problem 10CR

To determine

To prove : $\overrightarrow{FH}$ bisects $\angle EFG$

Explanation of Solution

Given information :

Here, we have given that $\angle 1\cong \angle 2$ and $\angle 1\cong \angle 3$

Proof:As, $\angle 1\cong \angle 2$ and $\angle 1\cong \angle 3$ ,

  $\Rightarrow \angle 2\cong \angle 3$

  $\therefore$

  $\overrightarrow{FH}$ bisects $\angle EFG$
