ellipse are 50mm away from mid point .Draw the ellipse. [16]

2. A circus man rides a motor bike inside a globe of 12meters diameter .The motor

bike has the wheel of 1 meter diameter .Draw the locus of the point on the

circumference of the motor bike wheel for one complete revolution. [16]

possible positions.

b) Two pegs fixed on a wall are 4.5m apart. The distance between the pegs measured

parallel to the floor is 3.6m. If one peg is 1.5m above the floor; find the height of

4. Draw the projections of a rhombus having diagonals 125mm & 50mm long the

smaller diagonal of which is parallel to both the parallel lines, while the other is

inclined at 300 to H.P. [16]

5. A pentagonal prism is resting on one of the corners of its base on the H.P. The

longer edge containing the corner is inclined at 450 to the H.P. The axis of the

prism makes an angle of 300 to the V.P. Draw the projections of the solid. [16]
