What is the difference between a regular hexagon and an irregular hexagon?

Answer 1

All hexagons have six sides.

If the six sides are of the same length and the angles formed by the six intersections of these lines are all identical, then it is a special hexagon called a regular hexagon.

If any of the sides is a different length than any other side or if any of the angles are a different size than any of the others, the hexagon is called an irregular hexagon.

Answer 2

Any regular figure has equal side lengths and angle measures, while irregular figures have different angle measures and/or different side lengths.
