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

[Free Registration/Login may be required to access all resource tools.] Determine the formula for finding the coordinates of a point on a line segment.

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

Provides examples and a video lesson that introduce fundamental statements of geometry.

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.

A wealth of resources to supplement instruction on parts of the circle. Find lessons describing chords, tangents, secants, and segments, as well as related practice quizzes and classroom activities.

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...

In this video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.

Learn all about the basic geometric constructions in this test prep lesson. You will explore line segments and points, and understand key terms like the terms parallel and perpendicular. Construction activities and interactive online...

A "convention" is "just the way a thing is done!". This reference material lists some common conventions (notational assumptions) for geometry and trigonometry.
