An octagon and a quadrilateral, respectively.
A polygon can have 8 sides but does not have to. The word "Polygon" is made up of two words: "poly-" and "-gon" which have Greek roots which mean "many" and "angle" respectively; literally a "polygon" is a "many angled shape". A polygon is any shape that has 3 or more sides. An 8 sided polygon is called an octagon (literally "eight angles").
A 10-sided polygon is a decagon.
A pentagon and a quadrilateral, respectively.
