What shape is a plane?

a plane shape is a shape that can be drawn with all its points in one plan A plane shape is a 2-dimensional shape with only (X) and (Y) measurements which are height and length. A square has 4 sides and 4 corners. A circle has one never ending line and no corners. A rectangle is longer than a square. A triangle has 3 sides and 3 corners. A hexagon has 6 sides and 6 corners. Any plane shape has the same amount of corners as sides. An octagon has 8, a decagon has 10, a pentagon has 5. Because a circle's line is never ending and curves in the same direction, a circle has an infinite line of symmetry.
