EXERCISE 1. A line AB has a length of 131 mm. Divide it graphically into 8 equal parts. 2. Divide a 90 mm long straight line into 3 parts in the proportion of 2 : 3 : 5. 3. Mark three points A, B and C at any convenient locations and draw a circle passing through these points. 4. Draw a tangent to a circle of diameter 50 mm from a point P, 110 mm away from the centre of circle. 5. Draw a common external tangent to two circles of diameter 100 mm and 60 mm whose centres are located at 110 mm apart. 6. In the above problem draw a common internal tangent. 7. Draw a common external tangent to two circles of diameter 80 mm each whose centres are located at 120 mm apart. 8. In the above problem draw a common internal tangent. 9. Draw a triangle of sides 60 mm, 45 mm and 50 mm. 10. Construct a pentagon of side 25 mm. 11. Construct a hexagon of side 30 mm. 12. Construct a heptagon of side 25 mm. 13. Construct a octagon of side 30 mm. 14. Construct a nanogon of side 20 mm. 15. Construct a pentagon, hexagon and octagon on a common side AB of 40 mm length.
