Angle:
In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays.
Angles are also formed by the intersection of two planes.
These are called dihedral angles.
We can name an angle in the following ways :
i) An angle can be named by its label, in the interior of the angle.
ii) It can also be named by just its vertex.
iii) By the degree the two intersecting lines make.
To name the angle with 3 letters, use a point on each ray of the angle, and list the letters with the angle's vertex in the middle.
The angle's name can then be ∠S, ∠RST, ∠TSR, or ∠1.
