Chapter 2.3, Problem 12PSB

To determine

To Draw: conclusions from given information.

Answer to Problem 12PSB

  $PQ\perp RT$ And $\angle PQR={90}^{\circ }$

Explanation of Solution

Given information: $\angle PQS={90}^{\circ }$

  

  $\because \angle PQS={90}^{\circ }$ (Given)

  $\because RQS$ is a line.

  $\therefore PQ\perp RS$ (as $\angle PQS={90}^{\circ }$ )

  $\therefore \angle PQR={90}^{\circ }$
