There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
Polygons
Pentagons have 5 sides and they can be regular or irregular
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".
A point has no corners and no sides. There are several geometic shapes with no corners and only one side. Some of the shapes are circle, oval, and sphere.
squares and rectangles. and trapazoids
well... theres a decagon(10 sides)...
Of some shape, Yes. Of other shapes, No.
no some shapes like the rhombus have 4 sides making it a quadrilateral but 2 of its sides are not parallel
rhombus
Shapes with many sides, Polygons tessellate well, Geometry fun.
A square -- has 4 sides a triangle -- has 3 sides A pentagon -- has 5 sides A circle -- has one side
