Regular shapes are shapes where all the sides and angles are equal. One example of a regular shape is a square because all the sides are the same and all the angles are 90 degrees.
There is no special name. The term irregular is not appropriate because a rhombus is irregular but it has equal sides.
All regular shapes have congruent sides.
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
A Square

A rhombus is the only shape besides a square that can have equal sides.
An equilateral triangle.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
It isn't really a square if it has no equal sides. A trapezoid can be drawn that has no equal sides, some can have two sides equal. Quadrilaterals include those 4-sided shapes with no sides equal but they also include all other 4-sided shapes. You would need to specify "Quadrilateral with no equal sides".
