Ex 4.1, 1 (iii) Construct the following quadrilaterals. Parallelogram MORE OR = 6 cm RE = 4.5 cm EO = 7.5 cm
In parallelogram,
Opposite sides are equal
∴ EM = OR = 6 cm
& ER = OM = 4.5 cm
So, we have 4 sides and 1 diagonal
Let’s construct it
Steps of construction
1. Draw diagonal PU of length 7 cm
2. Taking 6 cm as radius,
and E as center,
draw an arc on top of EO
3. Taking 4.5 cm as radius,
and O as center,
draw an arc on top of EO
4. Taking 4.5 cm as radius,
and E as center,
draw an arc on bottom of EO
5. Taking 6 cm as radius,
and O as center,
draw an arc on bottom of EO
6. Let M be the point where arcs intersect on top of PU,
and R be the point where arcs intersect below PU
Join EM, MO, ER, RO
Label the sides
∴ MORE is the required parallelogram
