Parallelogram in Space
A parallelogram PQRS has sides PQ = 60mm and QR = 40mm. PQ is parallel to both HP and VP, 25mm above HP and 30mm in front of VP. QR makes 35° with HP and is parallel to VP. Draw its projections.

Step-by-Step Construction
- 1
Draw PQ parallel to XY in both views (shows true length 60mm)
- 2
Mark P at 25mm above HP and 30mm from VP
- 3
From Q, draw QR: parallel to VP means perpendicular to XY in TV
- 4
QR makes 35° with HP, shown in front view
- 5
Complete parallelogram with RS parallel to PQ and SP parallel to QR
- 6
Verify: opposite sides equal and parallel
Pro Tips
- •Always verify your measurements with a scale before finalizing the drawing
- •Use construction lines lightly and darken the final solution
- •Label all important points and reference lines clearly
