Symmetries of Fan and Flower

Transcript

Symmetries of Fan and FlowerWe have to find Rotational Symmetries of these three Let’s try to find symmetries of all 3 Symmetry of FanFor a Fan Rotational Symmetry: The fan is shown as an example of rotational symmetry. The drawing has 3 blades, so it has 3 angles of symmetry ( 120^∘,240^∘, and 360^∘ ). Line of Symmetry: The 3-bladed fan does not have any lines of symmetry. If you try to fold it in half, the blades will not overlap perfectly. Symmetry of FlowerFor a Flower Rotational Symmetry: The yellow flower shown has 6 petals. It has 6 angles of symmetry (the smallest angle would be 60^∘ ). Line of Symmetry: The document uses a 6-petaled flower as an example of a figure with multiple lines of symmetry. The answer key for a similar 6-petaled flower at the start of the chapter confirms it has 6 lines of symmetry.
