There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
Both are quadrilaterals. A rectangle has 4 right angles, a rhombus has 2 pairs of equal angles (at opposite corners) A rhombus has 4 equal sides, a rectangle has 2 pairs of equal sides. The opposite sides in both shapes are parallel to each other.
Shapes having less than 4 sides or more than 4 sides are not parallelograms
There is no special name. The term irregular is not appropriate because a rhombus is irregular but it has equal sides.
not really a square and a diamond does
The two quadrilaterals with equal sides are the rhombus and square.
Squares
No, both shapes have all four sides equal.
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".
Square and rhombus.
A square is a regular polygon with 4 equal sides and 4 equal interior angles.
It is a square as square has 4 sides and all of them are equal. Also it has 4 corners.
Squares
it is the square
It all depends on the shape; different 2D geometrical shapes have different characteristics.Some specialized geometrical shapes:Square: 4 sides; 4 equal sides; 2 pairs of parallel sides; 4 right angles (90 degrees)* A square is a rectangle.Rectangle: 4 sides; 2 pairs of parallel sides; 4 right angles (90 degrees)* A rectangle is not a square.Triangle (equilateral): 3 sides; 3 equal sides; all angles 60 degreesTriangle (isosceles): 3 sides; 2 equal sides (usually the base is the odd one)Triangle (scalene): 3 sides; all uneven sides and anglesRhombus: 4 sides; 4 equal sides; 2 pairs of parallel sides; 4 equal anglesParallelogram: 4 sides; 1 pair of parallel sidesThese are the basic geometrical 2D shapes, but there are others that are more complex.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
lots of shapes have equal sides including the square(4), the regular hexigon(6), the regular pentagon(5) and most over regular shapes.
