# Whats a ray length

## Geometry/Points, Lines, Line Segments and Rays

These explanations on line-segment, ray and line will help the kids to understand the different fundamental element of geometry and their distinction. We then refer to "normal" space as 3-dimensional space. Line segment CD. Line vs ray Hi, Leslie. Similarly a geometrical ray is considered a special kind of line which starts from a fixed point and goes to any distance to the other direction of the starting point.

Video transcript What I want to do in this video is think about the difference between a line segment, a line, and a ray. It has no size i. Only one line can be drawn passing through any two points but a number of lines can be drawn through a point. An example of a plane is a coordinate plane. This right over here, you have a starting point and an ending point, or you could call this the start point and the ending point, but it doesn't go on forever in either direction.

So, it can be measured. A line, line segment and ray all are called one dimensional 1-D figures as they have only length.

Points that are on the same line are called collinear points. So obviously, I've never encountered something that just keeps on going straight forever. A line is defined as a line of points that extends infinitely in two directions.

One letter is written at the starting point of the ray and the other letter is written near the arrow end as AB and LM. Line segment AB.

Ask a Question or Answer a Question. To determine whether two sets have the same size, we can pair up the elements.
