not really a square and a diamond does
There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
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.
The shapes that have 3 sides and 3 vertices are called triangles. Triangles are classified based on the lengths of their sides and the measures of their angles. The three most common types of triangles are equilateral triangles (all sides and angles are equal), isosceles triangles (two sides and two angles are equal), and scalene triangles (all sides and angles are different).
There is no special name. The term irregular is not appropriate because a rhombus is irregular but it has equal sides.
A Square
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
No, both shapes have all four sides equal.
A regular polygon has all sides equal length, and all of the angles are equal.

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".
