# How Is A Ruler Different From A Straightedge?

A straight edge is a ruler that looks like an L and  you can measure at angles and more with it, a ruler is a straight instrument, and isn't used the same as a straight edge, it's smaller for one than the edge. Hope this helps, good luck.

I like this.It helped me
A ruler has marks on it that permit measurements to be made.
A straightedge is just a straight edge. It has no marks.

A straightedge has no form of measurement whereas a ruler measures feet, inches, centimeters, etc.

Straitedge has no marks
Segment ends between to points .______. rough example
Line <------> Of course it is a solid line; continues in both directions
Ray Starts at one point but keeps going (this one is harder to draw  .------>
I had this class recently so it is fresh in my mind
Bu bye

Ok so I understand, a line segment ends and a line is continues. And Rays start at a point, but can continue like sun rays? I feel utterly stupid right now, but I do understand!! Thank you
A line segment is a part of a line that has to end points
A line  is a group of points on a straight path that extends to infinity
a Ray it has one end point and extends to infinity in one direction..
Look it up on google foe examples.

A straight  edge is anything that can be used to make/draw a straight line. A school ruler  is a straight flat stick that has incremental marks on it to make measurements. Rulers do not have to be flat in order to be called a ruler.this is what I remember

That was pretty easy.  Now what is the difference between segments, lines and rays?
