About Cyclic Quadrilaterals
A cyclic quadrilateral (or inscribed quadrilateral) is a quadrilateral whose vertices all lie on a single circle. The sides satisfy specific geometric properties.
The area is calculated using Brahmagupta's formula: A = √[(s-a)(s-b)(s-c)(s-d)], where s is the semi-perimeter.
Frequently Asked Questions
- What if the sides don't form a cyclic quadrilateral?
- For any four lengths forming a quadrilateral, there exists a cyclic quadrilateral with those side lengths if the longest side is shorter than the sum of the others.
