A
line segment is a section of a line running between two points.
A
ray is the part of a straight line that extends infinitely in one direction from a fixed point.
Line, Ray, Line Segment, Plane, Point, Song
A song to help you learn Line, Ray, Line Segment, Plane, Point.
Lyrics:
Draw a line.
Make a ray.
Make a line segment.
It's so plane.
And take the point.
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.
Ray - A ray is part of a line that has one endpoint. It continues in one direction without ending.
Angle - An angle is formed when two rays share an endpoint. This is called a vertex.
Example:
How many line segments are in this rectangle?
Grade 3 Math, Lines, Rays, Points, Line Segments
Line
• it's in a straight path.
• goes in both directions.
• does not end ... so you can't measure it's length.
Ray
• it's straight.
• is part of a line.
• has one endpoint.
• goes in ONE direction.
Line Segment
• is straight.
• is a part of a line.
• has 2 endpoints that show the points that end the line.
