The right angle symbol is used to denote a right 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 with arc symbol.
The right angle with square symbol is used to represent a perpendicular angle.
In geometry, the perpendicular symbol is used to show that two lines are perpendicular to each other. Visually, the symbol is made up of two lines that form a perpendicular angle.
The spherical angle, ∢, is used in geometry to denote the figure formed by two intersecting lines and a spherical surface. It is also used in spherical geometry to describe the angle between two intersecting great circles.
The right triangle symbol.
A perpendicular angle is visually denoted by drawing a square at the vertex of the angle. The measured angle is equal to π/2 radians or 90°.
A right angle is an angle of exactly 90 degrees, a quarter of a full turn.
