Answer:
Point
Explanation:
An object of indeterminate size which marks a location in space is called a point.
A point in geometry has no dimension unlike a line which is one dimensional. In essence, like other bodies, we cannot specify any of the width, length or height of a point.
- Points are usually shown with dots.
- It has no width, length, breadth and other attributes that specifies it.
- Angle at a point is taken as 360° which is the same as the angle in a circle.
On the other hand, a line is a connects two or more points and it is one dimensional. They usually have lengths.
Therefore, an object of indeterminate size which marks a location in space is a point.
