The ‘∢’ (spherical angle) symbol is used in geometry to denote the figure formed by two intersecting lines and a spherical surface. In spherical geometry, it describes the angle between two intersecting great circles.
For example, in an equation like this:
This denotes the spherical angle formed by points A, B, and C, with B being the vertex of the angle.
In geometry, the angle symbol is used to denote an angle formed by three points. The middle point corresponds to the vertex at which the angle lies.
The right angle symbol is used to denote a right angle.
