Draw the following. In each case, the figure should contain at least one curved boundary.
A figure with exactly one line of symmetry
Draw a heart shape or teardrop shape. These have exactly one line of symmetry passing through the centre vertically, dividing the shape into mirror halves.
A figure with exactly two lines of symmetry
Draw an ellipse (oval). It has exactly two lines of symmetry - one horizontal and one vertical, passing through the centre.
A figure with exactly four lines of symmetry
Draw a shape like a four-petaled flower or a rounded square. These have four lines of symmetry - two through opposite 'petals' and two through the gaps between them.
Explanation
(a) A heart or teardrop has curved boundaries and exactly one line of symmetry. (b) An ellipse has curved boundaries and exactly two perpendicular lines of symmetry. (c) A four-petaled flower or similar shape has curved boundaries and four lines of symmetry.
