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.

Fourth graders investigate regular polygons. In this regular polygon lesson, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.

Explore lines and angles, and the relationship between the two.

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.

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

In this lesson, students will identify and draw lines, segments, rays, angles, and points.

You can pick up some valuable pointers on angles and lines here. When you finish working your way through the pages you can take an on-line "Test Bite," and check your understanding.

Explores how to measure the length of a line segment through examples and a video lesson. [0:40]

Learn how to construct bisectors of line segments and angles.

Construct a copy of a line segment in this interactive exercise.

This task provides a construction of the angle bisector of an angle by reducing it to the bisection of an angle to finding the midpoint of a line segment. Aligns with G-CO.D.12.

This fourth-grade geometry lesson teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the whole...

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.

This site from Advogato is all about angles. It contains information starting with what an angle is and what it looks like, all the way up to bisecting angles and theorems about angles. This is very good information for students just...

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 may be required to access all resource tools.] For this learning module, students examine line drawings to determine if angles are formed by intersections. Includes video demonstrating a sample problem [0:32] and...

In this task, 8th graders are presented with a drawing of two parallel lines connected through two line segments. They are given the measures of two angles and are asked to find a third. Aligns with 8.G.A.5.

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

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

Practice using your graphing calculator for drawing and labeling points, lines, planes, and angles. If you get stumped or if you would like to check your work, then select the View Solution button, which is located directly under each...

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.

This site provides definitions of different types of polygons and figures.

Students discover the shortest distance light travels from an object to the human eye, as the light from the object reflects off a single mirror. In the process they learn about reflection in a line, congruent angles, angle bisectors,...
