Draw a circle with radius 5 cm.
Draw a second circle with radius 3 cm, outside and just touching the most North-East part of the first circle.
Draw two small triangles, 4 cm apart, resting on top of the second circle.
Inside the second circle, arranged so that they are symmetrical about a vertical line through the centre, draw these four things:
• a small triangle at the centre
• two small circles 3 cm apart, above the triangle
• the bottom half of a circle, below the triangle.
