To draw the projection of the pentagonal prism, first draw the base which is a regular pentagon with 25mm sides. Then, extend the sides of the pentagon upwards by 60mm to represent the height of the prism. Next, draw the perspective view by projecting lines from the corners of the base to the corresponding corners on the top pentagon. Finally, draw the visible edges connecting the top and bottom pentagons to complete the projection of the pentagonal prism with the axis parallel to the vertical plane (vp).
A pentagonal prism has 10 vertices. A rectangular prism has 8 vertices. Therefore, a pentagonal prism has 2 more vertices than a rectangular prism.
