Chapter 1, Problem 16RP

Solution

To Prove: The congruency of $\angle 1$ with respect to $\angle 2$

Given information: $\angle 1={61.6}^{\circ }and\angle 2=61{\frac{3}{5}}^{\circ }$ provided in the question which will help to find the solution.

Proof: Here, $\angle 1=\angle 2$ (as given in the question)

By using angle property, we can say that

  $m\angle 1=m\angle 2={61.6}^{\circ }$

So that, $m\angle 1=m\angle 2$ (by using substitution)

Hence, by using congruence rule, we can say that

  $\angle 1\cong \angle 2$
