It is the pythagorean theorem. Used in finding the lengths of sides of right angled triangles.
a=b=3.60555
The formula for finding the angles is called " Pythagorean Thyrum " It states that a squred plus b squared equals c squared so therefore c squared minus a squared will equal b squared. i hope that helps
