Problem 13-1 Draw Projections of a Triangular Prism,

base40 mm side and axis 50 mm long, resting on one of its bases on the H.P. with a vertical axis perpendicular to VP

a)As the axis is perpendicular to the ground that is HP begin with the top view it will an equilateral triangle of sides 40 mm long with one of its sides perpendicular to XY.

b)Project the front view which will be a rectangle.
