This document defines and provides examples of different types of lines in geometry: - Perpendicular lines are lines that intersect at 90 degree angles. They can be labeled with a small box in the corner. - Parallel lines never intersect and are always the same distance apart. They point in the same direction. - The document provides instructions for using a set square and ruler to draw lines through specific points on a diagram.

1. Geometry
Lines
What will we learn today?
• Drawing lines with set square and
ruler

2. Let's recap!

3. Perpendicular Lines
Definition:
Lines that are at right angles (90°) to
each other.

4. Perpendicular
It means at right angles (90°) to.
How do we label perpendicular lines?
We can draw a little box in the corner.
The little box drawn in the corner, means
"at right angles"

5. Parallel Lines
Definition:
• Lines are parallel if they are always the
same distance apart and will never meet.
• They also point in the same direction.
In conclusion, parallel lines are
Always the same distance apart and never touching.
