Students make connections between the coordinate grid and Geometry by finding the distance of line segments using the coordinate plane. This lesson includes a detailed lesson plan, slides containing notes and problems, and a...

Join Joan the chameleon in an exploration of lines and slope. You'll be drawing lines, calculating slope, using equations and more!

Investigate finding the midpoint of a line segment and derive the formula for the midpoint of two points on a coordinate plane. This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.

Brush up on your math skills pertaining to lines, line segments, and rays then try some practice problems to test your understanding.

[Free Registration/Login Required] This lesson is an introduction to the basic geometric figures: lines, rays, and line segments. The definition and naming conventions for each figure are explained. An assessment section follows.

Students are to find different ways to make two line segments that touch seven pins. Materials needed include geoboards, rubber bands, geoboard paper and rulers.

This step-by-step tutorial teaches students how to construct a bisector of a segment and the bisector of an angle.

This site provides a step-by-step method to construct congruent segments and angles with a straight edge and compass.

Find a quick, concise explanation of Congruent Line Segments. Several examples are given and clearly explained.

The student will derive and use the slope and midpoint formulas to verify geometric relationship that include parallelism and perpendicularity of lines. Then, the student will determine an equation of a line parallel or perpendicular to...

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.

Learn all about lines. This lesson targets what is a line and the different types. Check-out the interactive simulations to know more about the lesson and try your hand at solving a few interesting practice questions at the end of the page.

Students act as civil engineers developing safe railways as a way to strengthen their understanding of parallel and intersecting lines. Using pieces of yarn to visually represent line segments, students lay down "train tracks" on a...

Explains the basic concept of lines and angles with step-by-step instructions and methods for solving specific problems on your own relating to this topic.

[Free Registration/Login Required] In this lesson, students will generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch and show the data by making a line plot. This lesson includes an...

Provides details about the properties of straight lines, types of straight lines, line segments, rays, curved lines, and types of angles.

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.

Get independent practice identifying points, lines, rays, planes and angles. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

[Free Registration/Login may be required to access all resource tools.] This study guide reviews how to measure the distance between two points and the Ruler Postulate. It also introduces congruency/congruent segments and midpoint.

A complete reference guide to points, lines, and planes. It provides definitions and interactive activities that enhance further explanation.

Second graders need to share their understandings of lines, line segments, shapes and attributes.
