Parallel, Perpendicular & Intersecting Lines
Parallel Lines are lines that are always the same distance apart. They will never cross or intersect. Make 2 parallel lines on your geoboard. Make 3 lines on your geoboard that are all parallel.
Intersecting Lines are lines that intersect or cross each other. Make 2 intersecting lines on your geoboard.
Perpendicular Lines are special intersecting lines. Where they cross, they form a right angle. Make 2 lines on your geoboard that are perpendicular.

3 Then Xavier said, "I think the first letter of my name has intersecting lines."
a Do you agree with him? Why or why not? If you do, draw an arrow to show where the 2 lines intersect.

3b Circle the letter that has 2 intersecting lines.
C (^) J X s
4 Write the first letter of your first name in this box. Label it to show any lines that are parallel, perpendicular, or intersecting. If the first letter of your first name is completely curved (like O or C), choose a different letter in your first or last name that has straight lines.
5 Circle True or False to show which statements below correctly descibe these lines.
a The two lines above are parallel.
b The two lines above are pependicular.
C The two lines above are interesecting.
True True True
False False False
6 Two lines that are not parallel and not perpendicular are called oblique lines. Circle all the pairs of oblique lines below.
