Polygons A polygon is a plane shape with straight sides.

QUADRILATERALS.  A plane shape with four straight sides is called a quadrilateral.  We name quadrilaterals by looking at the properties of their sides.

Objective: To describe properties 2 D shapes

Two-dimensional Shapes (2D) These shapes are flat and can only be drawn on paper. They have two dimensions – length and width. They are sometimes called plane shapes.

Polygons Two-dimensional shapes that have sides made from straight lines. E.g. triangles squares hexagons

Quadrilaterals Any two-dimensional shapes with four straight sides. E.g. square rhombus rectangle trapezium kite

Rectangle A four sided two-dimensional shape with two pairs of parallel sides that meet at right angles.

Kite A two-dimensional shape with two shorter sides of equal length and two longer sides of equal length.

Rhombus A two-dimensional four sided shape with opposite sides that are parallel and all the sides are the same length.

Trapezoid A two-dimensional shape with four sides. One pair of sides is parallel with one side longer than the other.

Pentagon A two-dimensional shape with five straight sides and five angles.

Hexagon A two-dimensional shape with 6 straight sides and 6 angles.

Octagon A two-dimensional shape with 8 straight sides and 8 angles.

Circle A round flat two-dimensional shape.

Square Two dimensional shape with 4 sides of the same length and 4 90° angles.

Triangle Two-dimensional shape with three straight sides and three angles. Can you name 4 different kinds?
