An octagon.
An eight-sided plane figure is an octagon. If the sides are all the same length, and the angles are all equal, it is a regular octagon.
If the sides are all equal, and opposite sides are parallel, then the angles are all equal (72º) and it is a 'regular hexagon'. A six sided plane figure is called a hexagon, as "hex" means "six."

This type of polygon is called a hexagon. "Hex-" is a greek root, meaning 6. A polygon is a geometric plane figure consisting of at least 3 straight sides and angles, such as a triangle or square. Because "hex-" means 6, you know that a polygon that has 6 sides and 6 angles is a hexagon. As another example, "octo-" means 8, so a polygon that has 8 sides and 8 angles would be called an octagon.
An octagon has 8 sides and 8 angles.
All octagons have 8 sides and 8 angles
