They are named for the number of sides and angles their shape posses. For example, an octagon has both eight sides and angles.
I am not aware of any other names that take in all its characteristics. It is a parallelogram but that does not reuire its angles to be 90 degreesl etc.
equal angle
There are infinitely many polygons so it would be impossible to name them all. For the names of those with a fewer sides see the related link.
Classifications by side length or comparison of angles and sides:scalene - no sides or angles equalisosceles - two sides and angles equal (congruent)equilateral - all sides and angles equal (all 60° angles)Classifications by included angles :right triangle - contains a 90° angle (right angle)oblique triangle - has no right angleacute triangle - contains all angles less than 90°obtuse triangle - contains one angle greater than 90°
Acute angles do not have specific names.

Regular square: A square with all equal sides and right angles. Rectangle: A square with all right angles but unequal sides. Rhombus: A square with all sides equal in length but angles are not necessarily 90 degrees.

A convex polygon with congruent sides and congruent angles is a regular polygon.Some regular pilgrims have specific names: Equilateral triangle and square
There are no angles: the only intersections are of curves.
Complimentary angles.
