a pentagon
A kite or arrowhead.
A 2-dimensional figure can have any number of sides more than 2.
A rhombus is a closed 2-dimensional figure with four straight sides of equal length.
A hexagon is a 2-dimensional figure with six sides. In general, a 2-dimensional figure with many sides is called a polygon.
If it is a 2-dimensional figure then it is a quadrilateral. If it is a 3-dimensional figure then it is a tetrahedron.
The formula for a rhombus is as follows: "a closed 2-dimensional figure with four straight sides of equal length".
A 2-dimensional figure with 12 sides is called a dodecagon. A 3-dimensional figure with 12 sides (faces) is called a dedecahedron.
A decagon is a 2-dimensional shape bounded by 12 straight sides. In a regular dodecagon all the sides are equal and all the angles are equal.
The shape can only be a rectangle! A rectangle is a four-sided 2-dimentional figure, where every angle is a right angle, opposite sides are parallel, but the 4 sides are NOT equal.
A polygon is a 2-dimensional closed figure that has at least three sides. A pentagon is a 2-dimensional closed figure that has five and only five sides, so it is a kind of polygon.
