Both, in a way. An octagon gets its name from the word meaning, "eight angles" so an octagon can have eight unequal sides. However, a regular octagon is a closed eight-sided figure with sides of the same length and internal angles of the same size.
An octagon is a polygon with eight sides and eight angles. All eight sides of an octagon are equal in length, and all eight angles are equal, measuring 135 degrees. These properties define the shape of an octagon and distinguish it from other polygons.
if the angles of a figure are the same but the sides aren't, it is similiar. Congruent is angles and sides exactly the same
...eight interior and exterior angles. ANGLES
A pentagon has five sides and five angles.
A convex figure has eight sides. What is the sum of its exterior angles?
Whether it is a regular or irregular octagon does not matter. An octagon is, by definition, a 2-dimensional figure with eight sides, and therefore with eight angles. A regular octagon will have eight equal angles and an irregular octagon will have eight angles some of which are not equal to the others.

A plane figure with eight sides is an octagon.

a circle
A hexagon has six sides and six angles.
A figure with 4 equal sides and 4 equal angles is a square :)
A figure with four equal sides and no right angles is a rhombus. A rhombus is comprised of two acute angles and two obtuse angles.
