Angles and Side Calculation\'s Online


Important Formula:
Sin(q) = Opposite / Hypotenuse
Cos(q) = Adjacent / Hypotenuse
Tan(q) = 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.

I want to calculate &
Opposite Side =
Hypotenuse Side =
Adjacent Side =
Angle q = [Max 90]
Angle b = (90-q) =
 

 
   
  


The formulae (formula) for finding angle and sides of triangle can be easily remembered using the sentence -Old Harry And His Old Aunt

Sin (q) = Old/Harry = Opposite/Hypotenuse
Cos (q) = And/His = Adjacent/Hypotenuse
Tan (q) = Old/Aunt = Opposite/Adjacent
