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.

A lesson plan to cover the standards about line segments. In this lesson plan, 2nd graders will measure and record the length of a line segment. Students will also compare lengths of a line but adding and subtracting line segments.

Reviews the characteristics of lines, lines segments, and rays, and presents questions for additional practice. Questions include hints.

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

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

Learn about line segments with this useful reference guide. Provides a detailed definition, examples, and an interactive activity that enhances further explanation. Includes links to related topics.

This robust lesson plan for upper elementary and middle school grades introduces the concepts for lines, rays, line segments, and planes. Resources are linked to it and ready for your use.

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.

Learn about congruent line segments with this helpful reference tool. Provides a detailed definition, examples, and an interactive activity that enhances further explanation. Includes links to related topics.

This interactive Java applet allows visualization of line segments and their slopes. The slope and how it is found is given for each line drawn by the user.

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.

This site contains a definition of a line segment. Includes a graphic and links to related sites.

Students will investigate patterns and make conjectures about geometric relationships.

Figure out the coordinates of a point between two other points that give a certain ratio. For example, find a point C so that it is two-thirds of the way between point A and B. Students receive immediate feedback and have the opportunity...
