AAS Triangle Calculator (Angle-Angle-Side)

Your details

One of the two known angles (in degrees). Must be between 0 and 180, and the two angles together must be less than 180.
deg
The second known angle (in degrees). Angle A + Angle B must be less than 180.
deg

Triangle solved: angles 40.00, 25.00, 115.00 degrees.

  • This is an obtuse triangle and a scalene triangle (all sides different).
  • The three sides are 16.0000 cm, 10.5196 cm, and 22.5594 cm.
  • Area = 76.2722 cm² and perimeter = 49.0791 cm.
  • Inradius (r) = 3.1081 cm and circumradius (R) = 12.4458 cm.

Next stepVerify your result by checking that a/sin(A) = b/sin(B) = c/sin(C). If the ratio holds, the Law of Sines was applied correctly.
