Using the activity center and the Navigator software, the students will review ordered pairs, and the equations for horizontal, parallel, and perpendicular lines.

Angles, parallel lines, and transversals are explained through examples and a video lesson. [1:01]

Learners explore the definitions and properties of the perpendicular bisector. The interactive activity includes an applet to explore the properties of the perpendicular bisector.

Students can review basic geometric terms using these self-check, multiple choice questions. Three levels of questions are provided.

[Free Registration/Login Required] This flipchart defines Parallel, Intersecting, and Perpendicular lines. It also provides opportunities to practice working with Parallel, Intersecting and Perpendicular Lines!

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...

A comprehensive guide for learning all about perpendicular lines with definitions, how to draw them, solved examples, and practice questions

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.

[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.

A tutorial on slope with many step-by-step examples. The tutorial clarifies what slope is, how to find slope between two points on a graph, and how slopes of parallel and perpendicular lines are related.

Provides a definition and examples of perpendicular bisectors.

The lesson teaches students about an important characteristic of lines: their slopes. Slope can be determined either in graphical or algebraic form. Slope can also be described as positive, negative, zero or undefined. Students get an...

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.

The students will explore angles, rays, line segments, perpendicular lines, parallel lines, and two-dimensional figures through the use of the book Shape Up! Fun With Triangles and Other Polygons by David A. Adler. They will also...

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.

Explains how to draw a perpendicular bisector and provides a definition of the perpendicular bisector theorem.

Twenty-two problems present a practice finding the slope of a line. The solutions are only available with a paid subscription.

This step-by-step method teaches students to construct a perpendicular to a line through a point on--or off--the initial line using compass and straight edge.

Students learn to draw a segment and its perpendicular bisector. They understand right angles and congruent segments. Students observe that changing the length or orientation of the segment changes the perpendicular bisector.

MathWorld's definition of a perpendicular bisector, with illustrations to show the different uses of the perpendicular bisector.

Students learn about chords of a circle. They draw a line perpendicular to the chord and passing through the center of the circle. They explore the lengths of the two segments of the chord. They investigate with a different chord and...

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...
