Answer Posted / deepak kumar(yadav)
there are four angle i.e 1'st,2nd,3rd &4th.in fist angle we m
ove anticlock wise in 90degree(the rule is that horizontal line move in anticlock wise direction).so we make drawing in 2nd quardent.In second angle we move 90degree in clockwise direction,but if we move 90degree in clockwise direction it cause overlap due to this reason we never make drawing in second angle(the rule is vertical line moves clockwise),in 3rd angle we move 90degree anticlock(as per first quardent rule),so we make drawing in 3rd qurdent,IN 4TH quardent we move clockwise in 90degree it cause overlap due to this reason we never make drawing in 4th quardent.
