Have ideas for future Parent Homework Help stories?.Need help or advice about your child’s learning?.Have questions or ideas about this story?.As always, playing math games at home is a great way to reinforce math skills learned in school.This is one of the most common mistakes students make. So, using the example G.-–.H>, this ray would be read “ray GH”, and not “ray HG”. A ray must be read in the direction of the arrow. The ray is the only one that doesn’t follow this rule.The line segment could read either “line segment EF” or “line segment FE.” Using the examples from the Naming Lines, Lines Segments and Rays above, the line could read either “line AB” or “line BA”. As your child is naming lines and line segments, be sure he notices that they can be read in either direction.(The drawing should form a cross shape.) What To Watch For Your child would draw:Ī-B> with CROSSING ray AB. This would read: “Draw ray AB that intersects with line CD”. A typical question would look like this:ĭraw ->AB that intersects with CD. Your child will likely be asked to draw lines, line segments and rays at school.Parallel lines are two lines that are equal distance from one another (if the two lines were extended infinitely, they would never cross.We say a ray has one endpoint and goes without end in one direction. It has staring point but has no end point. In Geometry also, a ray starts from a point and may go to infinity. The rays start from sun and go in all directions and reach to us. Intersecting lines are lines that cross one another. The light rays come out of it and move away.As your child learns about lines, line segments and rays, he will also be introduced to third and second grade math skill vocabulary words such as intersect and parallel.It too is labelled with uppercase letters on each end.
Each endpoint is labelled with an uppercase letter.Ī ray has one endpoint, and an arrow on the other end. There are 2 points on the line that are labelled with uppercase letters.Ī line segment has an endpoint on both ends, indicating that there is a distinct beginning and end. This is to indicate that the line goes on forever in both directions. You may have noticed that a line has arrows on both ends. We typically name a line, line segment or ray using uppercase letters. It does not have a beginning or an end.Ī line segment is a part of a line, defined by two endpoints.Ī ray is a part of line that has only one endpoint, and extends indefinitely in one direction. What is it?Ī line is defined as an infinite set of points forming a straight path, extending in both directions. Lines, line segments, and rays are all second and third grade math concepts, and although they are similar, they are not the same. What exactly do these geometry terms mean? Read on to find out. Well, your 2nd or 3rd grader just might challenge your definition.
