The length of a straight line from the centre of a circle to the edge of the circle.
A straight-edge
A geometrical construction can be made with with a straight edge and a compass.
With a protractor and a straight edge
A straight edge
A Ruler
A ruler has markings, a straight edge does not. In "straight edge and compass" constructions, you are not allowed to mark the straight edge. Things that are impossible using only a straight edge and compass are possible if markings are allowed (for example, it's possible to trisect an angle using a marked straight edge).
Generally a ruler is a straight edge, but it can be anything... I generally just use a spare pencil.
The line round the edge of the circle.
An edge is a straight line as part of a polygon. It can also be the straight line joining two faces of a solid which has polygonal faces.
A straight edge or a ruler are used to construct straight lines.
An angle whose measure is exactly 180° - a straight line
The length of a straight line from the centre of a circle to the edge of the circle.
A ray in math begins as a point (or dot, in laymans terms) with a straight arrow coming from it.
No. But there are straight edge "groups" that are a lot like gangs. But no, straight edge itself is not a gang, and a straight edge person is not a gang member.
2 points. However, the farther apart the 2 points the striaghter the line will be, unless you move the straight edge!!.
A straight edge is used for making perfectly straight lines when drawing. The straight edge is placed on the paper and you use the edge to draw against.
