Question

A pentagonal lamina of side 25mm rests on the HP on one side of its edges such that the surface is inclined at 45° to the HP and the edge on which it's rests is inclined at 60° to the VP Draw it's projections

Answer 1

Answer:

first draw a regular pentagon on hp

Then in second step draw pentagon of 45 degree than in third step merge them and finally on fourth stage draw it's image

Explanation:

Answer 2

Answer:

To draw the projections of the pentagonal lamina, we first need to understand the given information. The lamina is a pentagon with sides of length 25mm, and it is resting on one of its edges such that the surface is inclined at 45° to the HP and the edge on which it rests is inclined at 60° to the VP.

Explanation:

To draw the projections, we follow the following steps:

• Draw the front view of the pentagon as a regular pentagon of side 25mm.
• Draw the top view of the pentagon by projecting the vertices of the front view perpendicularly onto the HP.
• Draw the edge view of the pentagon by projecting the edge on which it rests at 60° to the VP.
• Join the corresponding points of the top and edge views to obtain the true shape of the pentagon.
• Finally, shade the visible surfaces of the pentagon to obtain the complete projections.

The resulting projections will show the pentagonal lamina resting on its edge at an angle of 60° to the VP, with one of its surfaces inclined at 45° to the HP.
