We have,
HE=6cm.
EL=4.5cm.
∠H=60
o
∠E=105
o
∠P=120
o
We shall find the fourth angle first.
Sum of all the angles of a quadrilateral=360
o
∴∠L=360
o
=(60
o
+105
o
+120

)
∠L=750
o
Step (1):-first draw base HE=6cm.
Step (2):- Construct ∠H=60
o
Step (3):- Construct ∠E=105
o
On this line of ∠E cut an arc at 4.5 cm.
Step(4):- Construct ∠L=75
