In a right-angled triangle, the base is the side on which the triangle stands. The perpendicular is the side that makes a right angle with the base.

The three sides of a right-angled triangle are:

Base: The side that touches the other angle

Perpendicular: The side that makes a right angle with the base

Hypotenuse: The largest side, which is opposite to the right angle

Any of the two sides other than the hypotenuse can be chosen as the base for performing calculations.

In a right-angled triangle, the other two sides are called the legs. The legs are interchangeably called the:

Base: The adjacent side

Height: The perpendicular side

In a right angled triangle, the three sides are called: Perpendicular, Base(Adjacent) and Hypotenuse(Opposite). Perpendicular is the side that makes right angle with the base of the triangle. The largest side side which is opposite to the right-angle(90 degree) is known as the Hypotenuse.
