For given positions of solid solid is just tilted to some angle with V.P and previously given axis is perpendicular to V.P so front view gives circle and next with some given angle shape will change to some irregular shape of circle and triangle.

When axis of solid is perpendicular to V.P it is indirectly saying that base is parallel to vertical plane so projection on to it gives true shape of base and n we can project and find or dimensions.

The flat surface of hemisphere will have section of circle with radius equal to radius of sphere. Here hemisphere is placed on H.P so that its flat surface is inclined to H.P so it gives semi circle from front view and ellipse from top view.

For given positions of solid solid is made acute angle with H.P and previously given axis is perpendicular to H.P so front view gives rectangle and next with some given angle shape will rotate totally.

Prism is a polyhedron having two equal and similar faces (bases or ends), parallel to each or and joined by or faces which are rectangles. So re exist 3 x number of sides of base of edges in prism.

As 1^st stage is to keep solid in simple position and given is front view it is triangle and n rotated to an angle of 30 degrees with H.P which again gives triangle and n rotating 45 degrees with V.P which gives triangle with base as ellipse.

Given a square pyramid which means projection to its base gives square shape and or orthographic views give triangle. Here given is pyramid whose axis is inclined to V.P so its front view will be irregular pentagon and top view will be isosceles triangle.

Given a regular hexagonal pyramid made to place on profile plane on its base, in which position pyramid may place like this top view and front gives triangle in particular isosceles triangle as pyramid given is regular one and side view gives hexagon.

As in 1^st stage cube is to be placed in position occurred when diagonal of base perpendicular to V.P so top view gives square and n rotated so as to keep one of corners only on H.P so top view will be irregular hexagon n if we make diagonal perpendicular to V.P top view will be irregular hexagon.

Given three spheres of same radius are placed on H.P each touching or two, line joining centers of spheres gives equilateral triangle. From front view spheres seem to be intersecting circles but from top three circles will be seen.
