Both lines & angles are two different terms.
The line means a straight part of a line. In contrast, an angle means the sequence between two lines.
Line segment
The term 'line segment' means a line that includes two endpoints. One endpoint is present at the beginning, and the other is at the end.
Ray
The meaning of ray is a line in which only there is a single endpoint.
Angle
When the initial point of two rays intersects at a single point, it forms an angle.
Types of Angles
Different types of angles are there that contain different meanings. Each type of angle is discussed below:
-
Acute angle:
It is a type of angle that is smaller than 90°.
-
Right angle:
It is a type of angle that always makes a 90° angle.
-
Straight angle:
One of the angles is a straight angle that is always equal to a 180° angle.
-
Adjacent angle:
The adjacent angle is a type of angle that consists of common vertices.
-
Obtuse angle:
Such types of angles always lie between 90° and 180°.
-
Reflex angle:
This angle is always greater than 180°.
