Parallel Lines Teacher Resources

Describes and gives good examples relating to the slopes of parallel and perpendicular lines.

This activity has students discover the relationship between parallel and perpendicular lines and their slopes. After constructing these objects using CABRI Geometry II for the TI-89, slopes are measured. [Requires Adobe Reader.]

This lesson introduces students to Activity Center and is intended to help students interpret whether lines are parallel or perpendicular. [Requires Adobe Reader.]

This video lesson demonstrates how to determine if linear equations are parallel, identical, or intersecting. Students can check their understanding with an assessment.

In this lesson plan, students use line segments, angles, and parallel and perpendicular lines in order to create a one point perspective drawing.

Get independent practice working with parallel and perpendicular lines. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

This activity will help students understand the relationship between the slopes of parallel and perpendicular lines.

This site gives a description of parallel planes along with a visual representation. Be sure to use the links to related terms, everyday examples, more information, and the interactive check point involving parallel planes located in the...

This activity is for use as a formative assessment tool after the introduction and overview of parallel and perpendicular slopes.

Washington State University provides a lesson on finding the slope of an equation and putting the equation into the desired form. The site also contains informatinon concerning parallel and perpendicular lines.

Students learn to develop the equation of a line from its graph. They also learn to write the equation of a line from the slope and the y-intercept, a point and the slope, and two points. They also investigate slopes of lines that are...

In this activity, students use the Cabri software to mark points, draw lines, construct parallel and perpendicular lines, angles, bisectors, and triangles. They learn how to use the tool to measure angles.

Find the gradient, equations and intersections of medians, altitudes and perpendicular bisectors using our knowledge of the mid-point as well as parallel and perpendicular lines.

Understand the step-by-step processes used to create accurate geometric figures.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students about corresponding angles, and how to use them to determine whether or not lines are parallel. Students examine guided notes, review...
