It is an irregular shape
In a triangle with no sides congruent we call it scalene.
A shape that does not have equal sides is called an irregular shape.
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 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.
This shape is called an icosikaitera. All of the sides of the icosikaitera are all of the same equal length.
