1. The rectangle is resting on its horizontal plane (HP) on one small side that makes a 300 inclination to the vertical plane (VP). 2. The surface of the plane makes a 450 inclination to the HP. 3. In the front view, the true shape of the rectangle will be shown since the surface is inclined to the HP. The side making a 300 inclination to the VP will be vertical in the front view.

1. Problem 1: Read problem and answer following questions
