1. Construct the following quadrilaterals:
(i) Quadrilateral MORE

MO = 6 cm, OR = 4.5 cm,

M = O = R =

(ii) Quadrilateral PLAN

PL = 4 cm, LA = 6.5 cm,

P = A = N =

(iii) Parallelogram HEAR

HE = 5 cm, EA = 6 cm, R =

(iv) Rectangle OKAY

Ans.  (i) Given:  MO = 6 cm, OR = 4.5 cm,

M = O = R =

To construct: A quadrilateral MORE.

Steps of construction:

(a) Draw a line segment MO = 6 cm.

(b) Construct R =  and taking radius 4.5 cm, draw an arc taking O as centre, which intersects at R.

(c) Also construct an angle  at R and produce the side RE.

(d) Construct another angle of  at point M and produce the side ME. Both sides ME and RE intersect at E.

It is the required quadrilateral MORE.

(ii) Given:  PL = 4 cm, LA = 6.5 cm,

P = A = N =

To construct: A quadrilateral PLAN.

To findL =

Steps of construction:

(a) Draw a line segment PL = 4 cm.
