Spatial sense is an important cognitive skill for children. They start to look at the world as a space full of shapes. In this lesson, we will classify two-dimensional figures into categories through understanding their attributes and properties.

See the fact file below for more information on the Classifying Two-Dimensional Figures or alternatively, you can download our 26-page Classifying Two-Dimensional Figures worksheet pack to utilise within the classroom or home environment.

Key Facts & Information

TWO-DIMENSIONAL SHAPES AND THEIR ATTRIBUTES

  • Two-dimensional shapes can be analyzed through their number of sides or edges, corners or vertices, and the characteristic of the lines, whether straight or curved.
  • An edge is a line segment connecting one vertex to another.
  • A vertex or corner is a point where two line segments meet.

CIRCLE

  • A circle is a closed two-dimensional figure in which all points in the plane is equidistant from the center. The distance from the center to the outer line of the circle is called the radius. The diameter, however, goes straight across the circle through the center.

POLYGON

  • A polygon is a two-dimensional shape made up of straight lines on a flat surface that are connected to form a closed figure.
  • Polygons are usually defined by the number of sides that they have.
  • TRIANGLE
    • A triangle is a three-sided polygon that has three edges and three vertices. It has also three angles whose sum is equal to 180 degrees.
    • Right triangle
      A triangle that has one right angle
    • Scalene triangle
      A triangle that has no side of the same length
    • Acute triangle
      A triangle that has three angles that measure between 0 degrees to 90 degrees
    • Isosceles triangle
      A triangle that has at least two sides of the same length
    • Obtuse triangle
      A triangle that has one angle that measures greater than 90 degrees and less than 180 degrees
    • Equilateral triangle
      A triangle that has three sides of the same length
  • QUADRILATERAL
    • A quadrilateral is any shape that has four sides and four vertices. This includes the square, rectangle, rhombus, parallelogram, and trapezoid.
    • The internal angles of all quadrilaterals add up to 360 degrees.
    • Square – a shape that has four equal sides and four right angles
    • Rectangle – a shape that has four sides and four right angles
    • Rhombus – a shape that has four equal sides and no right angles
    • Parallelogram – a shape that has four sides with opposite sides parallel and equal
    • Trapezoid – an isosceles trapezoid has two parallel sides and equal base angles, and its non-parallel sides are of equal length. Another attribute of a trapezoid is having two parallel sides while its side lengths and angles are not equal.
  • Pentagon – a shape that has five sides and five vertices
  • Hexagon – a shape that has six sides and six vertices
  • Heptagon – a shape that has seven sides and seven vertices
