AAS Triangle Calculator: Solve for Unknown Angles and Sides

Calculate AAS Triangle Sides & Angles

Angle A must be > 0 and < 180.
Angle B must be > 0 and < 180.
Side a must be > 0.

Unlock the secrets of triangles with our AAS Triangle Calculator. Quickly determine all unknown angles and sides (a, b, c, A, B, C) when you know Angle-Angle-Side (AAS). Perfect for students, engineers, and anyone needing precise geometric solutions. Input your values and get instant results!

Formula:

The AAS (Angle-Angle-Side) method uses the Law of Sines and the fact that the sum of angles in a triangle is 180°.

  • Sum of Angles: A + B + C = 180°
  • Law of Sines: a/sin(A) = b/sin(B) = c/sin(C)

Where A, B, C are angles and a, b, c are the sides opposite those angles, respectively.
