Lines, Line Segments, Rays, and Angles - Practice 15.1
Is it a line, line segment, ray, or angle? Identifying geometric figures is the focus. In addition to identification, learners recognize right angles or tell if an angle is less than or greater than a right angle. They tell if lines are...

Construct and Measure Lines, Segments, Rays, and Angles Using Geometer's Sketchpad
Sixth graders construct points, lines, rays, line segments and angles using Geometer's Sketchpad, label all points and measure each constructed item, print their constructions, and complete question sheet to demonstrate understanding.
Points, Lines, and Rays - Problem Solving 15.1
Here is a set of five word problems in which geometers draw and identify points, lines, segments, rays. They determine if lines are perpendicular or parallel. This is a concise, yet applicable worksheet to help learners grasp the...
