Angle Calculation is a site that provides a free tool that allows you to calculate the "angle" of a right triangle just by entering the "length of the base" and "height". If you know the base and height, you can easily find the angle (gradient/inclination) and area.

Angle (°)
-°
Angle (radians)
-rad
Diagonal side (c) Hypotenuse

How to use

  1. The "base (a) adjacent side" and "height (b)" of the right-angled triangle for which you want to find the angle are ) Opposite Side.
  2. The "Angle (°)", "Angle (radian)", "Diagonal Side (c)", and "Area (S)" will be calculated automatically.

Right triangle angle calculation

The basic way to calculate the angles of a right triangle is to use trigonometric functions. Since one angle of a right triangle is 90°, it is necessary to calculate the remaining two angles. It is common for this to be the case.

  • Adjacent side (a) BaseThe side adjacent to the angle θ (other than the hypotenuse). Base
  • < (b) HeightThe side opposite the angle θ. Side equivalent to height
  • Hypotent side (c)The longest side of a right triangle. Diagonal side

Angle (θ) Formula for finding the angle θ

θ = tan −1 (b/a)

Example of calculation for finding the angle (θ)

Adjacent side (a): 4

Opposite side (b): 3

θ = tan−1(0.75 ) ≒ 36.87°
