A decagon has 10 equal sides while a square has 4 equal sides
octahedron is a regular square bipyramid but a square bipyramid can be non-regular
A square, pentagon, decagon, octagon are always regular polygons.
ofcourse no, quadrilateral means its a poligon with 4 sizes, like square, rectangle, rhombus, trapezium, etc... And Decagon, means its a poligon with 10 sizes. a decagon is a polygon with ten sides. a quadrilateral is a polygon with four sides. "deca" = 10 "quadri" = 4
km is a measurement of length, while a square km is a unit of area.
The answer depends on the specific shape and size of the decagon.
A decagon is a two-dimensional shape with ten sides. In a regular decagon each of the sides will have an equal length.* * * * *AND each interior angle will be the same measure. If either the sides or angles are not ALL equal to one another, the shape is not regular. Consider quadrilaterals, for example. A rhombus has equal sides but the angles are not all the same so it is not regular. A rectangle has equal angles but the sides are not the same. So it is not regular either. The only regular quadrilateral is a square.
any regular * square * rhombus * pentagon * hexagon * heptagon * octagon * nonagon * decagon * so on so on
the Square and the ParallelogramIf there can be more sides then an y of the regular polygons with an even number of sides fill the bill: regular hexagon, octagon, decagon...
A decagon.
No mathematical difference.
A decagon has 10 sides and a square has 4. So 10-4=6 more sides
