Instructions

Enter values three of the six sides and angles of the triangle and the other three values will be computed. The number of significant values entered will determine the number of significant figures in the results.

Frequently Asked Questions

Q: I like your triangles, especially the ones that have interior angles not summing to 180 degrees. Neat! Try sides equal to 1,2,2.

A: Because each of the sides you entered has so few significant figures, the angles are all rounded to come out to 80, 80, and 30 (each with one significant figure). Entering sides of values 1.00, 2.00, and 2.00 will yield much more acurate results of 75.5, 75.5, and 29.0.
