In this triangle worksheet, students use similar figures to find the length of one side of two similar triangles. They find the area of a triangle inscribed in a rectangle. This two-page worksheet contains eight problems.

In this math worksheet, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

In this activity, students will make a gauge to track wind direction.

Students 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. Students identify different geometric shapes in the...

In this frequency worksheet, students use the standard rules for Scrabble to find the abbreviations used on the board. Then, the determine the frequency as stated in the chart shown to represent the correct number of letter tiles.

Fourth graders use computer drawing tools to create a house of geometric shapes.

Students examine a powerful tool that can be used in the study of motion. They use VideoPoint to measure an aspect of an organism's motion: speed, acceleration, center of mass.

Recognize parallel and perpendicular lines in geometric figures and pictures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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

Practice drawing parallel and perpendicular lines, line segments, and ray. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Provides examples and a video lesson that illustrates parallel and perpendicular lines.

Use your knowledge about the slopes of parallel and perpendicular lines to solve some problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] Identify intersecting, parallel and perpendicular lines in a plane

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

This is an introductory lesson on graphing parallel and perpendicular lines. The students will have a good visual on how these lines relate to each other. This also illustrates how to determine equations in slope-intercept form of a line...

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...

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.]

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.

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

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

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...

Write the equation for a line that is a parallel or perpendicular to a line given in slope-intercept form and that goes through a specific point. Students receive immediate feedback and have the opportunity to try questions repeatedly,...
