Problems on Oblique Plane
Example No – 02
A square lamina of 50 mm side rests on one of the
corners on the H.P. The diagonal through that corner
makes 30˚ to the V.P. The two sides containing this
corner makes equal inclinations with the H.P. The
surface of the lamina makes 45˚ to the H.P. Draw the
TV & FV of the lamina.
