4. A precise location with no length, breadth, or height

Answer

2. The shortest distance between two points with two distinct endpoints
- A line segment is a part of a straight line that has two distinct endpoints and contains all points
between them.

Ray

A ray is like a line that starts at one specific point and keeps going forever in one direction. The point
where it starts is called the starting point or initial point of the ray.

For instance, the light from a flashlight or a beam from a lighthouse is similar to a ray—it starts at the
source and keeps going. We represent a ray by its starting point and another point on the ray,

like Ray , where A is the starting point.

Angle
An angle is formed when two rays share a common starting point. For example, imagine if you have

rays that start from the same point B, they form an angle. The common point B is

called the vertex of the angle, and the rays are called the arms of the angle.

Naming an Angle
 To name an angle, you can simply use the vertex, calling it "Angle B."
