Parallel, Intersecting, and Perpendicular Lines

Use what you know about parallel and perpendicular lines to write equations! Learners take an equation of a line and write an equation of a line that is parallel or perpendicular using slope criteria. They then solve problems to...

This resource should be called "All About Lines, and Then Some!". Packed full of all the key components of linear functions, learners review how to set up different equations, find intercepts, and graph. All the main topics are included...

The coordinate plane links key geometry and algebra concepts in this approachable but rigorous unit. The class starts by developing the distance formula from the Pythagorean Theorem, then moves to applications of slope. Activities...

Provide the definitions of parallel and perpendicular lines, as well as the relationships between their slopes. Two examples explain the process of finding the equation of either a perpendicular or parallel line to another line through a...

What do parallel and perpendicular lines have to do with slope? The video highlights the importance of slope when graphing parallel and perpendicular lines. The instructor shows several examples of lines that are parallel and...

Perpendicular lines are all right. Using the definition of perpendicular, the video lesson introduces perpendicular lines.The portion a basic geometry playlist makes connections between the rules of parallel lines and perpendicular lines.

Perpendicular lines intersect to form right angles - four of them to be exact. Vertical angles, congruent angles, 90 degrees each, these are some of the special properties of perpendicular lines. Watch this video to find out a couple...

What kind of lines have slopes that are the opposite reciprocal of each other? Parallel lines? No. Parabolas? No. Perpendicular lines? Yes! Watch and listen as the instructor demonstrates how to make these determinations about...

Geometers identify and determine angle pair relationships when two parallel lines are intersected by a transversal. They review the concepts of angles by watching streaming video clips online, read definitions of lines and angles from...

Enhance your class's understanding of linear equations by extending their study to parallel and perpendicular lines. Young mathematicians learn the relationship between the slopes of parallel and perpendicular lines. They then use that...
