It is an irregular shape
In a triangle with no sides congruent we call it scalene.
It is an irregular shape or polygon that doesn't have all sides equal
A shape where all the sides are equal and all the angles are equal. If all sides are equal but angles or not, it is equilateral. If it is vice versa, it is equiangular.
You would call it an irregular polygon. Afraid not. There is no specific name, except in the case of a triangle: scalene. You should not call it simply an irregular polygon, because a regular polygon implies that ALL sides are equal and ALL angles are equal. So a rhombus, where all four sides are equal, is still irregular.
A shape with 100 sides is called a hecatontagon. The prefix "hecto-" means 100 in Greek, so a hecatontagon is a polygon with 100 sides. It is a regular polygon, meaning all its sides are of equal length and all its angles are equal.
A square is a four-sided shape with all sides equal and all angles equal.
Square. By definition, its sides must all be equal.
As long as the angles are all equal as well then it is a regular shape.
A shape with six sides is a hexagon. A hexagon with all sides and angles equal is a regular hexagon.
all the sides of the shape are equal (:
When all its sides and angles are equal.
You just call it a decagon. If all the angles and sides are equal then it's a regular decagon. If not, it's an irregular decagon.
