Perpendicular Lines

Study the diagram. The line $l$ is perpendicular to line $\mathrm{m}$

Identify any two-line segments for which PE is the perpendicular bisector.

Study the diagram. The line $l$ is perpendicular to line $\mathrm{m}$

Does $\mathrm{P}\mathrm{E}$ bisect $\mathrm{C}\mathrm{G}$?

Determine whether the following model is perpendicular lines or not:

The letter $\mathrm{V}$.

Determine whether the following model is perpendicular lines or not:
The line segments forming the letter $\mathrm{‘}\mathrm{L}\mathrm{’}$.
 

Determine whether "The lines of a railway track" is perpendicular lines or not.
 

Study the diagram. The line $l$ is perpendicular to line $\mathrm{m}$

Is $\mathrm{C}\mathrm{E}=\mathrm{E}\mathrm{G}$?

There are two “set-squares” in your box. What are the measures of the angles that are formed at their corners? Do they have any angle measure that is common?

Let $\overline{\mathrm{P}\mathrm{Q}}$ be the perpendicular to the line segment $\overline{\mathrm{X}\mathrm{Y}}$. Let $\overline{\mathrm{P}\mathrm{Q}}$ and $\overline{\mathrm{X}\mathrm{Y}}$ intersect in the point $\mathrm{A}$. What is the measure of $\mathrm{\angle }\mathrm{P}\mathrm{A}\mathrm{Y}$?

Check whether the model is perpendicular lines or not:

The adjacent edges of a tabletop.
