Projections of Plane Surfaces 11 Alpha angle Engineering Graphics Computer Aided Engineering Drawing

An isosceles triangular plate of negligible thickness has base 25mm long and altitude 35mm. it is so placed on HP such that in the front view it is seen as an equilateral triangle of 25mm sides with the side that is parallel to VP is inclined at 45° to HP. Draw its top and front views. Also determine the inclination of the plate with reference plane

A triangular lamina of 25mm sides rests on one of its corners on VP such that the median passing through the corner on which it rests is inclined at 30° to HP and 45° to VP. Draw its projections.
