Identify Line Types: Identify Types of Lines

For Students 6th - 12th Standards
If lines aren't parallel or perpendicular, then what are they? An interactive lets users rotate a line to change its orientation with respect to another line. It then indicates whether the lines are parallel, perpendicular, or...

Intersecting and Parallel Lines

For Students 6th - 8th Standards
Sometimes line segments just refuse to meet. Young mathematicians connect houses on an interactive map using line segments. They must then determine whether these line segment pairs are intersecting or parallel.
