What is the difference between intersecting and perpendicular?

Perpendicular lines are a special kind of intersecting. They cross at a right angle, shown by the small square mark. Crossing lines without that mark are just intersecting, so the sheet wants the more specific name when the mark is there.

Why do the arrows and dots matter so much?

They are the whole difference between the figures. A segment and a line can look identical in the middle. Only the ends tell you whether the path stops or runs on forever, which is the 4.G.A.1 idea.

4th grade lines, rays & segments worksheets

Lines, rays, and segments worksheets for fourth grade alternate two jobs: identify a drawn figure (point, line, line segment, or ray) and tell how a pair of lines meet: parallel, perpendicular, or plain intersecting.

Free printable PDF worksheet, aligned to Common Core 4.G.A.1.

Each print is a different sheet with its own answer key. You don't need to sign up.

The kind of problems you'll get

Name each figure: line, ray, or line segment.

A drawing has one endpoint and one arrow continuing away from it.
Answer: It represents a ray.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

What's on a 4th grade sheet

Lines rays and segments. Name each figure: line, ray, or line segment. 10 problems per page.

Every version prints on US Letter or A4, with its answer key after the problems.

How to teach this

Make the ends the first question every time: arrows or dots, and how many of each? Two arrows, one arrow, two dots: line, ray, segment, in that order. For the line pairs, extend them with a ruler when in doubt. Parallel lines never meet no matter how far they run, and perpendicular needs the square mark at the crossing, not just a crossing that looks square. A flashlight beam makes a memorable ray: one endpoint, then on and on.

Watch for: Kids call every straight drawing a line. A line has arrows on both ends, one arrow makes a ray, and two dots make a segment. Kids call any crossing lines perpendicular. Perpendicular needs a square corner, shown by the small square mark.
