A fine dot made by a sharp pencil or a geometrical figure having no length, breadth and height as called a point.
2. Line segment
If we join two fixed points then the figure formed is called line segment.
If we extend the two end points of a line segment in either direction endlessly then it is called a line.
It has no definite length.
If we extend one end point of a line segment endlessly then it is called a ray.
An angle is formed by intersecting two rays. The intersection point is the common initial point of these two rays which is called as vertex of the angle. We use the symbol ‘ ∠’ to denote the measure of the angle
• An angle is an inclination between two rays with the same initial point.
In this fig. the angles are ∠∠
