Parallel and Perpendicular Lines Worksheets
What is the Difference Between Parallel and Perpendicular Lines? A line that crosses or intersects another line at 90 degrees is known as the perpendicular line. To represent a perpendicular, we draw a small square at the corner that forms the right angle. Parallel lines are defined as the two lines drawn at some distance apart. These lines neither intersect nor touch each other. For two lines to be parallel, they are drawn in the same plane. Parallel lines help us understand the relationships between the sides of numerous shapes. Shapes like square, parallelogram, and rectangle have sides that are parallel to each other. As parallel lines continue without intersecting each other, they have the same slope. On the other hand, perpendicular lines intersect at 90 degrees; their slopes are the negative reciprocals of each other.
Getting a Tan...
Did you hear about the geometry teacher who took his vacation
over Spring Break on an island in the Bahamas?
He came back a tan-gent.
