What are the basic building blocks of geometry?
Point-a point specifies only location. It has no length ,width, or depth.We usually represent a point with a dot on paper and label it and make it have dimensions, while a true points dimension is 0.
Line-a line has only one dimension: length. It contains forever in two directions (so it has infinitive length), but it has no width at all. A line connects two points.
Line segment-a line that has two end points.
Plane-a plane is a flat, two dimensional object.
Ray-a line with one end point
Collinear-a line on the same line
Coplanar-a plane on the same plane
