Practice 3-7: Slopes of Parallel and Perpendicular Lines

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...

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this instructional activity, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals...

Parallel or perpendicular? It's a slippery slope. This inquiry-based lesson focuses on the slope relationships between parallel and perpendicular lines. Class members follow the day-to-day layout of instruction activities and after the...

For this Algebra I/Algebra II/Geometry worksheet, learners examine the slopes of parallel and perpendicular lines and the relationship to the equation of the line. The four page worksheet contains explanation of topic, worked examples,...

In this Algebra I/Algebra II worksheet, students examine slope to determine if the given lines are parallel or perpendicular.  Students determine the equation of lines that are either parallel or perpendicular to the given line.  The two...

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...

Young geometers get some solid skills practice in evaluating slopes. Beginning with the basics of slope through two points and progressing through properties of parallel and perpendicular lines, the building of skills is gradual and...

Ever ponder parallel and perpendicular lines? An engaging video first investigates how the slopes of lines indicate whether two lines are parallel or perpendicular. It goes on to show how to use the equations of two lines to tell whether...

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...

High schoolers investigate parallel and perpendicular lines. They use Cabri Jr. to construct and explore the relationships between the slopes of parallel and perpendicular lines. The drawing and measurement tools available with Cabri Jr....
