[Free Registration/Login Required] This flipchart defines and gives opportunities to work with parallel and perpendicular lines. Prentice-Hall, bsee, Parallel, Perpendicular, 5.8, Algebra.

Students can use a graphing calculator to explore graphs of parallel and perpendicular lines. Students will find that parallel lines have the same slope and different y-intercepts and that the slopes of two perpendicular lines are...

Students can use TI 73 calculators to explore equations that create parallel and perpendicular lines. Teacher will use the screen capture feature of the Navigator system to display students graphs and equations to discuss observations to...

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.]

In this activity, students investigate how equations of parallel and perpendicular lines relate to each other. They use the drawing and measurement tools of Cabri Jr. to explore the slopes of lines. [Requires Adobe Reader.]

[Free Registration/Login may be required to access all resource tools.] Use their slopes to determine if two lines are parallel or perpendicular.

Students use Cabri Jr. App to investigate the slopes and equations of parallel and perpendicular lines.

This site displays formulas and examples, pertaining to slope, for parallel and perpendicular lines.

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

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

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

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

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

Learners exhibit comprehension of advanced mathematics skills in Geometry. The questions check understanding on parallel and perpendicular lines.

In this activity, students create a slope triangle and understand the concepts of slope and the equation of lines. They realize that slope is constant at all points along a fixed line. They also explore the slopes of parallel and...

Not only does this site show what the slope-intercept form is, but it helps you find the slope and the intercept of a line. There is also additional information on parallel lines, parametric form, and the distance between two points.

Characteristics of a line are explained to students through four different lessons. Topics include intercepts, slope, and special line cases. The lessons have an overview, materials, procedures, and evaluation techniques.

Brush up on your math skills relating to parallel and perpendicular lines then try some practice problems to test your understanding.

Three resources for teaching slopes and equations of lines: a lesson with a formula for finding slope, different equations for lines, and several examples; a fourteen-question quiz covering slope, perpendicular and parallel lines, and...

[Free Registration/Login Required] This flipchart is designed to review differences between parallel and perpendicular while providing students ample opportunities to locate examples of each. A United Streaming video is included as well.

This lesson explains what are parallel and perpendicular lines and includes varied exercises and a video that shows how to draw a perpendicular line and a rectangle using a protractor or a triangular ruler.

Understand how to find the slope of parallel and perpendicular lines.
