About these lines, rays and line segments worksheets
A line goes on forever in both directions and is drawn with an arrow at each end. A line segment is part of a line with two endpoints, so it can be measured. A ray has one endpoint and goes on forever in one direction. An angle is two rays that share an endpoint.
Each one is named with letters for its points. Line AB is written with a two-headed arrow over AB, line segment CD with a bar over CD, and ray EF with an arrow over EF. A ray is always named from its endpoint first. In angle ABC, the vertex B goes in the middle.
These worksheets start with a chart, then naming figures, drawing them through labeled points with a ruler, and finding them in one figure. Every practice page has an answer key.
Standards
CCSS.MATH.CONTENT.4.G.A.1Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
How to use them
- Teach from the Lines, Rays and Line Segments chart.
- Use Sheet A, then Sheet B, which adds points and angles.
- Use Draw Lines, Rays and Segments with a ruler.
- Finish with Find Them in a Figure.
Teaching tips
- Ask: how many endpoints? Two is a segment, one is a ray, none is a line.
- Ray AB and ray BA are different rays.
- Line AB and line BA are the same line.
Questions teachers and parents ask
What is the difference between a line, a ray and a line segment?
A line has no endpoints and goes on forever both ways. A ray has one endpoint and goes on forever one way. A line segment has two endpoints.
How do you name a ray?
Start with its endpoint, then any other point on it: ray EF starts at E and goes through F.
