Points, Lines, Rays - 3rd Grade
Learn to identify geometric figures such as points, lines, line segments, rays, and angles.
Key vocabulary is covered and there are practice problems as well.
Point - A point is an exact location or position.
Line - A line is straight and continues in both directions.
Line segment - A line segment is part of a line. It has two endpoints.
