Triangle Calculator

Step 1:

Enter the values of any two angles and any one side of a triangle below which you want to solve for remaining angle and sides.

Triangle calculator finds the values of remaining sides and angles by using Sine Law.

Sine law states that

$\frac{a}{\text{sin}A}=\frac{b}{\text{sin}B}=\frac{c}{\text{sin}C}$

Cosine law states that-

$a^2=b^2+c^2-2bc.\text{cos}\left(A\right)$
$b^2=a^2+c^2-2ac.\text{cos}\left(B\right)$
$c^2=a^2+b^2-2ab.\text{cos}\left(C\right)$
