A rectangle is a shape that has four sides with two parallel lines.
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.
A shape with four sides is called a quadrilateral.
NO!!! If all four sides where equal , then you would have a 'Rhombus'. A Kite shape has four sides, two adjacent sides are of equal length.
The general name for a plane shape with four sides is a quadrilateral.
A shape with four sides and three vertices does not exist in Euclidean geometry. In Euclidean geometry, a shape must have the same number of sides as vertices. Therefore, a shape with four sides would have four vertices.
as shape with four sides is generally a squre but a group of shapes with four sides are called quadrelaterals
square
A shape with nine sides is called a nonagon.
