Perpendicular

In geometry, two lines or planes are said to be perpendicular if they intersect at a right angle, which is an angle of degrees.

For example, in the Cartesian coordinate system, the -axis and -axis are perpendicular to each other.

Similarly, the edges of a square or rectangle are perpendicular to each other, as are the faces of a cube or rectangular prism.

The symbol for perpendicularity is ⊥. For example, if you have two lines, and , you can write to mean “line is perpendicular to line ”.

Angle

An angle is a measure of rotation or turning and is usually measured in degrees or radians. In geometry, an angle is the figure formed by two rays, sharing a common endpoint called the vertex.

Perpendicular Symbol (⊥)

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.
