Construction
To construct geometrical shapes
A "straightedge" person was originally someone who didn't do any of the following; * take/use drugs * drink any alcohol * smoke * have sex * eat dairy products * eat meat now-a-days, most kids call themselves straightedge if they don't do the top 3 in the list, and any kids that don't do anything in the list are called "hardcore straight-up straightedge kids" Answer A straightedge is a piece of wood or plastic to help in drawing straight lines. A ruler is a straightedge, but a straightedge may not be a ruler. Both have a straight edge, certainly, but a ruler also has marked gradations for measuring things.
a straightedge need not have measuring increments (inches, centimeters, etc.) while a ruler is a straightedge with measuring increments

To draw a line parallel to line MN, you can use a straightedge and a pencil. Start by marking a point anywhere on the paper and label it as point A. Then, place the straightedge on point A and line MN, ensuring that the straightedge is parallel to line MN. Next, draw a line extending from point A along the straightedge, and this new line will be parallel to line MN.
