Geometry contains the properties of geometric objects basically angles, straight lines and circles. Geo mean earth and metron mean s measurement.
It is a straight line between two points. It has two end points. A point is always represented in capital letters.
It has only one end point. All the set of points are only in one direction.
Angle is formed at the common or intersection point between two rays or line segments. Common end point is called as vertex. Here Q is the vertex.
Line doesn’t have any endpoints. It is straight and can be extended indefinitely in both directions.
