1. Draw the projections of the regular hexagon of side 20 mm kept such that one of sides lie on the V.P. and is perpendicular to the XY line. The hexagonal plane makes an angle of 30° with V.P. 2. Draw the projections of the regular pentagon of 25 mm side. It has one side at 20 mm above the H.P. and nearest vertices of that side is 20 mm in front of V.P. Its plane is inclined at 45° to the H.P. and perpendicular to the V.P. Draw its projections and show its trace. 3. Draw the projections of a regular hexagon of 20 mm side, having one of its sides in the H.P. and inclined at 45° to the V.P. and its surface making an angle of 30° with the H.P. 4. Draw the projections of a circle of 50 mm diameter resting in the H.P. on a point A on the circumference, its plane inclined at 45° to the H.P. and the diameter AB making 30° angle with V.P.
