What is the diffreference between a ruler and a straightedge?
A ruler is usually graduated so that it can be used to measure lengths. A straight edge is just that: it has no marking to help you measure lengths.
What is a straightedge?
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.
What are the 4 basic tools of geometry?
A protractor, a compass, a ruler, and a straightedge
How can you measure a hexagon with no protractor or ruler?
Measuring implies using a measuring device of some kind. If you mean to construct a hexagon without a protractor or ruler, that's different. Constructions in geometry require only a compass and a straightedge (a ruler, but you ignore the numbers). A hexagon can be made of 6 equilateral triangles; choose any length for the side and construct them connected together, using only the compass to set the length and the straightedge to draw straight lines between points.
What is the difference between a ruler postulate and a protractor postulate?
a ruler measures the distance and a protractor measures the angles
