Chapter 2, Problem 11RP

To determine

To Prove: The congruency of the $\angle ABE$ with respect to $\angle CBD$

Explanation of Solution

Given information: $\angle ABD$ and $\angle CBE$ are right angles is provided in the question which will help to find the solution.

Proof: Here, $\angle ABD=\angle CBE$ (Right angles)

  $\angle ABE+\angle EBD=\angle CBD+\angle DBE$ ( $\because \angle EBD=\angle DBE$ )

  →$\angle ABE=\angle CBD$

Hence, $\angle ABE\cong \angle CBD$
