Question

A perpendicular is drawn to a line segment $\overline{MN}$ at N using a protractor and a point P is marked on it. Which of the following is true?

• A. $\overline{MP}$ $\perp$ $\overline{NP}$
• B. $\overline{MN}$ $\perp$ $\overline{MP}$
• C. $\overline{MN}$ = $\overline{MP}$
• D. $\overline{MN}$ $\perp$ $\overline{NP}$

Answer 1

The correct option is D $\overline{MN}$ $\perp$ $\overline{NP}$


The angle formed between $\overline{MN}$ and $\overline{NP}$ is 90${}^{\circ }$.
Hence $\overline{MN}$ $\perp$ $\overline{NP}$.
