Example 04 on Projection of Solids

A square prism 35 mm sides of base and 60 mm axis length rests on HP on one of its edges of the base. Draw the projections of the prism when the axis is inclined to HP at 45 degrees and VP at 30 degrees.

Can anybody say y we need to take beta angle here as in question it didn't mentioned as corner

[@VijethaVardhanRN]

Since the axis is inclined to one principle plane, its length is reduced and again inclined to another plane so we must take the apparent angle.

[@edumasters.2877]

Can u please tell in solids when to use false angle and when not to use it

[@VijethaVardhanRN]

When the line (base edge, longer edge, axis) is inclined to both HP and VP then we construct the apparent/False angle due to reduced length of line...

[@sharanya4850]

Sir how do we get to know we are getting apparent length and we need to cut the arc ??

[@VijethaVardhanRN]

If any line is inclined to both principal planes, then obviously we need to draw the apparent angle

[@Royal-gamerz07]

Sir please make on square pyramid

[@VijethaVardhanRN]

It is already available in playlist

[@taqdeesfatima4596]

this is not a square prism. it is a square base pyramid

[@VijethaVardhanRN]

It's absolutely perfect
Pyramid front view will be triangle
Prism Front view will be rectangle
