Rotational Symmetry A powerpoint presentation by Carmelo Ellul Head of Department (Mathematics) This powerpoint show is based on questions 1 and 2 of worksheet WS 90 s taken from the Formula One Maths Teacher’s Resource pack B 1 (Chapter 19 page 211)

Rotational Symmetry: WS 90 s Exercise 1: Which of these shapes have rotational symmetry? State the order of rotation for each shape. Rotational Symmetry of order 2 Rotational Symmetry of order 1 Rotational Symmetry of order 2 Rotational Symmetry of order 4

Rotational Symmetry: WS 90 s Exercise 2 (a): Complete the diagram so that the final shape has a rotational symmetry of order 2. Order of Rotation 1 2

Rotational Symmetry: WS 90 s Exercise 2 (b), (c) Complete the diagrams so that the final shapes have a rotational symmetry of order 2. Order of Rotation 2

Rotational Symmetry: WS 90 s Exercise 2 (d) Complete the diagram so that the final shape has a rotational symmetry of order 4. Order of Rotation 2 4

Rotational Symmetry: WS 90 s Exercise 2 (e), (f): Complete the diagrams so that the final shapes have a rotational symmetry of order 4. Order of Rotation 2 4

Rotational Symmetry: WS 90 s Exercise 2 (e), (f) Complete the diagrams so that the final shapes have a rotational symmetry of order 8. 2 Order of Rotation 4 8 RESTART END SHOW
