Further Explanation;

Circle

• A circle is a shape with all points the same distance from its center. It is one of the important shapes in geometry.
• A circle locus would be defined as a set of points at a given distance from a given point in a 2-dimensional plane.
• The given distance is the radius and the given points is the center of the circle.
• The diameter of a circle is equal to twice its radius (d equals 2 times r). The circumference of a circle is the line that goes around the center of the circle.

An angle

• An angle is defined as the union of two rays with a common endpoint.
• The common end point is known as the vertex of the angle while the rays are known as the sides of the angle.

Line segment

• A line segment is a piece of a line that has two endpoints.

A ray

• It is a part of a line with one end point and proceeds on in one direction.

A line

• A line refers to collection of line along a straight path proceeding in opposite directions with no endpoints.
