2. a) Draw the following lines used in projection. Answer
जनम्नजलजखि ल इनों को खींचे
i) Extension line ii) Leader line iii) Construction line
b) Draw the projection of a line AB, whose end A is in HP and 10 mm in front of VP. The
line makes an angle of 30° with VP and 60° with HP. The line is 50 mm long. Answer
एक 50 mm लं ी रे ख , जिसक A end HP में व VP से 10 mm आगे है। रे ख HP से 60° व VP से 30°
क कोण न िी है रेख AB क प्रक्षेपण करें।
3. A right regular pentagonal prism side of base 25 mm and axis 50 mm long lies on HP on
one of it's rectangular faces such that the axis is parallel to HP and inclined at 30° to VP.
Draw the projection of the solid. Answer
एक regular pentagonal prism, जिसकी base की भुि 25 mm और axis 50 mm लं ी है, अपनी एक
rectangular face पर िमीन पर लेट है। Prism की axis HP से सम न ंिर है व VP से 30° क कोण
