Respuesta :

Irregular hexagons (Meaning 6 sides, irregular is optional) and quadrilaterals.

As seen from the figure:

Group 1: It consists of three closed figures each having six sides. So these are all hexagons.

Group 2: It consists of three closed figures each having four sides.

All four are quadrilaterals.

So we can say that group 1 consists of hexagons and group two consists of quadrilaterals.
