AAS Triangle Calculator This AAS triangle calculator solves a triangle in the angle-angle-side case, where you know two angles and a side that is not between them. Enter Side A together with the two angles, and the calculator finds the third angle and the — free online calculator.

Formula

b = a × sin(angle2) / sin(angle1)
  • AAS Triangle Calculator calculates its result from Side A, Angle 1 (degrees), Angle 2 (degrees). It uses the formula b = a × sin(angle2) / sin(angle1). Change any input to recalculate the result instantly.
  • The main inputs are Side A, Angle 1, Angle 2. Enter them in the units and format shown in the calculator.
  • Keep comparable quantities in compatible units whenever the formula combines or compares them.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: AAS Triangle

Inputs
  • Side A: 5
  • Angle 1: 50 degrees
  • Angle 2: 60 degrees

Using Side A = 5, Angle 1 (degrees) = 50, Angle 2 (degrees) = 60, the calculated result is 5.8086858706.
