Khan Academy: Parallel and Perpendicular Lines

Here is a parallel and perpendicular lines worksheet which has learners respond to 10 questions that require them to identify lines and draw lines.

Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...

Fourth graders create a dance with a partner that shows parallel and perpendicular lines. For this lines lesson plan, 4th graders create symmetrical designs and line pairs with their partner.

Parallel lines never intersect, and perpendicular lines intersect at a 90 degree angle. Learn how to identify parallel and perpendicular lines.

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

Recognize parallel and perpendicular lines in geometric figures and pictures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice drawing parallel and perpendicular lines, line segments, and ray. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] Students practice identifying parallel and perpendicular lines after watching a video tutorial.

Learn the properties of parallel and perpendicular lines so that you can easily identify them. [2:08]

This activity provides an opportunity for students to build an understanding of parallel and intersecting lines.
