Understanding Rotational Symmetry: Determining the Order of Shapes

This educational resource focuses on recognizing the order of rotational symmetry in various shapes. It explains how shapes can fit onto themselves during a complete 360-degree rotation. For instance, a square has an order of rotational symmetry of 4, as it fits on itself four times, while a heart has an order of 1, fitting onto itself only once. The material provides interactive examples, inviting learners to explore and discover the symmetry properties of different shapes. Master the concepts of rotational symmetry to enhance geometric understanding!

  3. Remember your MARGIN !!! DATE Objectives: To be able to recognise the order of rotational symmetry of any shape

  4. Rotational Symmetry • The order of rotational symmetry of a shape is determined by how many times the shape fits onto itself during a 360° turn. (Example 1) • Every shape has an order of rotational symmetry, even if it is order 1. (Example 2) • Have a look at the following shapes…
