WebFeb 21, 2024 · Worksheet. This KS3 worksheet gives 14 different 2D shapes and asks students to find the order of rotational symmetry for each. Shapes include polygons and … WebNote, a rectangle has two (not four) lines of symmetry and a circle has an infinite number. If rotating a shape through a certain angle produces an identical shape, it has rotational symmetry. If the shape can be rotated 4 times before returning to its original shape (e.g. a square), it has "rotational symmetry of order 4". open houses long island ny
