Triangle Angles and Side Calculation Online

Please select the option and enter required values then press calculate button:

I want to find	Angle (θ) Opposite side Hypotenuse side Adjacent side
and	Angle (θ) Opposite side Hypotenuse side Adjacent side

Opposite Side :
Hypotenuse Side :
Adjacent Side :
Angle θ :[Max 90]
Angle β : (90-θ) =

 

Important Formula:

Sin(θ) = Opposite / Hypotenuse

Cos(θ) = Adjacent / Hypotenuse

Tan(θ) = Opposite / Adjacent

Select what (angle / sides) you want to calculate, then enter the values in the respective rows and click calculate.

If you want to calculate hypotenuse enter the values for other sides and angle.
