Question

Problem 10-1. (fig. 10-6): A line PQ, 90 mm long, is
in the H.P. and makes an angle of 30° with the V.P. Its
end P is 25 mm in front of the V.P. Draw its projections.​

Answer 1

Explanation:

given,

angle is 30 degree

25mm is in front of VP

and 90mm long and is in the HP

Answer 2

Refer the attachment

Construction:

• Draw a line PQ of 90 mm length
• Draw another parallel line at a distance of 25 mm from the XY axis of 90 mm length
• By putting the compass on point P' make an angle of 30°
• Extend this line upto 90 mm and mark it as P'Q'
• Now project the line P'Q' on the H.P
• Mark the line as PQ''
• Given below is the projection thus formed
