No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
Most shapes do not have equal sides. In nature, shapes with equal sides are the exception rather than the rule.
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".
Any regular shapes have equal sides, including squares and equilateral triangles. Irregular shapes can also have equal sides, but not equal angles.
Any shapes that have seven sides.
Any regular polygon. And some irregular polygons which will have some adjacent sides equal - for example, a kite or an arrowhead (chevron).
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
Names for shapes that have equal sides are called EQUILATERAL.
The two quadrilaterals with equal sides are the rhombus and square.
Circles, some triangles, and irregular polygons
Some shapes having four equal sides include rhombus, square, diamond, parallelogram with four equal sides, and oblique-angled equilateral parallelogram.
The Correct Answer is Irregular
2d shapes that do not have equal sides do not usually have special names.
No, both shapes have all four sides equal.
Equilateral shapes. They can be polygons with any number of sides and, apart from a triangle, they need not be regular.
The shape that has not got equal side is a rectangle
An equilateral triangle.
A rhombus is the only shape besides a square that can have equal sides.
isoceles triandle, square
not really a square and a diamond does
There is no special name. The term irregular is not appropriate because a rhombus is irregular but it has equal sides.
Shapes that do not have equal sides is called a quadrilateral. They include an irregular quadrilateral, rectangle, or a parallelogram.
A regular polygon has all sides equal length, and all of the angles are equal.
An infinite number. A polygon with any number of sides can be equilateral (ie have sides of equal length).
Four equal sides make up a square. The sides may be any size, as long as they are equal. A square is one of the most basic shapes.
