What is a Plane Shape? Definition and Examples


What is a plane shape? A plane shape, also called two-dimensional shape or plane figure, is a geometric figure that is completely flat. In other words, the figure has no thickness.

In fact, the expression two-dimensional refers to a figure that has two dimensions - length and width.

Since a plane shape has only length and width, but no depth, it makes sense that the figure will be flat.

Examples of plane shapes

  • Rectangles
  • Squares
  • Trapezoids
  • Circles
  • Pentagons
  • Hexagons

The expression two-dimensional figure can also be written as 2D figure.
