Young scholars explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Young scholars identify different geometric...

Given points that two lines go through or the graph of each line, classify the lines as parallel, perpendicular, or neither. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

Given points that two lines go through or the graph of each line, classify the lines as parallel, perpendicular, or neither.

Given characteristics of two lines, such as slopes and equations, the student will determine whether the lines are parallel, perpendicular, or neither.

[Free Registration/Login may be required to access all resource tools.] This lesson covers determining if two lines are parallel, perpendicular, or neither and finding the equation of perpendicular lines to a given line.

The student will verify theorems about angles formed by parallel lines cut by a transversal and apply these relationships to solve problems.

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

Northeast Parallel Architecture Center, Syracuse University provides a brief definition of the slopes of parallel and perpendicular lines

Twenty-two problems present a variety of practice working with perpendicular and parallel lines. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...
