Introduction to Four Sided Shapes

Hello, Year 5! Today, we are going to learn about four-sided shapes, also known as quadrilaterals. These shapes have four sides, four corners (or vertices), and four angles. Let’s explore some of the most common types of four-sided shapes together!

Key Types of Four Sided Shapes

  1. Square
    • Definition: A square has four equal sides and four right angles (90 degrees).
    • Example: Think of a chessboard square!
  2. Rectangle
    • Definition: A rectangle has two pairs of equal sides and four right angles.
    • Example: A door is usually shaped like a rectangle.
  3. Rhombus
    • Definition: A rhombus has four equal sides, but the angles are not necessarily right angles.
    • Example: A diamond shape is a rhombus.
  4. Parallelogram
    • Definition: A parallelogram has two pairs of equal sides, and the opposite angles are equal. The angles are not right angles.
    • Example: A slanted rectangle can be a parallelogram.
  5. Trapezium (or Trapezoid)
    • Definition: A trapezium has one pair of parallel sides.
    • Example: The shape of a roof can resemble a trapezium.

Key Rules to Remember

  • Angles: The sum of all angles in any four-sided shape is always 360 degrees.
  • Sides: The lengths of the sides can vary, which helps to define the type of four-sided shape.

Tips and Tricks

  • Visuals Help: Draw the shapes to see their properties better. Label the sides and angles!
  • Use Everyday Objects: Look around your home for examples of these shapes. This makes learning fun and relatable!
  • Practice: The more you practice identifying and drawing these shapes, the easier it will become.
