Drawing and identifying pairs of lines

Determine if the given pair of lines is parallel, perpendicular, or neither.

• Parallel

• Perpendicular

• Neither

This is an example of:

• Perpendicular lines

• Parallel lines

• Intersecting lines

Which lines appear parallel?

•

• 
• 

What are parallel lines?

• Lines that form square corners
• lines that never intersect
• lines that pass through the same point
• lines that curve on an angle

What does parallel mean?

• lines or objects that are side by side and have the same distance continuously between them?

• an object with four sides and all sides are different lengths

• the point where two lines meet making a right angle

• two lines of different lengths pointing in opposite directions

A (8, 5), B (4,2)

C (3,3), D (7,0)

The lines AB and CD are...

• Parallel

• Perpendicular

• Neither

Line Segment AB is perpendicular to line CD. Line CD is perpendicular to line segment EF. What is the relationship between Line Segments AB and EF?
