**Problem 1**:
Rectangle 30mm and 50mm sides is resting on HP on one small side which is 30^{o} inclined to VP,
while the surface of the plane makes 45^{o} inclination with HP. Draw it’s projections.

**Construction**

**Step 1.** Draw a rectangle abcd of sides 30mm & 50mm, which is parallel to HP.
This is the top view of the rectangle. Now, draw the projection of it's sides above
the XY axis. This is the front view of the rectangle i.e. a'b'c'd'.

**Step 2.** Now, the front view a'b'c'd' of the rectangle makes 45^{o} inclination
to the HP. Draw it's projection below XY axis, which gives the top view a_{1}b_{1}c_{1}d_{1}.

**Step 3.** Now, make 30^{o} inclination of one of the small side of rectangle a_{1}b_{1}c_{1}d_{1}.
to the VP. Finally
draw the points a_{1}'b_{1}'c_{1}'d_{1}' as shown above .

**Problem 2** : A circle of 50 mm diameter is
resting on Hp on end A of it’s diameter AC
which is 30^{o} inclined to Hp while it’s Tv
is 45^{o} inclined to Vp. Draw it’s projections.

** Construction**

**Step 1.**. Firstly, draw a circle of 25 mm radius(or 50 mm diameter) parallel to HP.

This is the top view of the circle. Name it abcd as shown in figure & draw it's
projection above the XY axis, which is the front view of the circle i.e. a'b'd'c'.

**Step 2.**. Now, the front view a'b'd'c' of the circle makes 30^{o} inclination
to the

HP. Draw it's projection below XY axis, which gives the top view a_{1}b_{1}c_{1}d_{1}.

**Step 3.** Now, make 45^{o} inclination of the diagonal a_{1}c_{1} to the VP. Finally
draw the points a_{1}'b_{1}'c_{1}'d_{1}' as shown above .

**Problem 3** : A rhombus of diagonals 40 mm and 70 mm long respectively has
one end of it’s longer diagonal in HP while that diagonal is 45^{o} inclined to HP.
If the top-view of the same diagonal makes 35^{o} inclination with VP, draw it’s projections

**Construction**

**Step 1.**. Draw a rhombus abcd of diagonals 40 mm and 70 mm long respectively parallel
to HP. This is the top view of the rhombus. Now, draw the projection of it's sides
above the XY axis, which shows it's front view i.e. a'b'd'c'.

**Step 2.**. Now, the front view a'b'd'c'of the rhombus makes 45^{o} inclination to
the

HP.Draw it's projection below XY axis, which gives the top view a_{1}b_{1}c_{1}d_{1}.

**Step 3.**. Now, make 35^{o} inclination of the longer diagonal a_{1}c_{1} to the VP.
Finally
draw the points a_{1}'b_{1}'c_{1}'d_{1}' as shown above .
