Can this calculator handle an isosceles trapezoid?

Yes, the tool includes special cases for isosceles and right trapezoids, automatically calculating angles and median when the appropriate side lengths are entered.

What if I only know the area and one base?

You would need to provide the height and the other base length, or the leg lengths, to determine the missing dimensions, as the calculator requires multiple inputs to compute all outputs.

Does the tool distinguish between a trapezoid and a rectangle?

The calculator notes that every rectangle is a trapezoid since it has at least one pair of parallel sides, but a trapezoid is not necessarily a rectangle.

How are the interior angles determined?

The angles α, β, γ, and δ are calculated based on the provided side lengths and height, with the tool explaining that the parallel bases create specific angle relationships.
