Frequently Asked Questions
What does Heron's formula need?
It needs only the three side lengths of a triangle, with no angle or height, to find the area.
Why might it report no triangle?
If any side is longer than the sum of the other two, the sides cannot close into a triangle, so the calculator reports an error.
