Question: 1 Construct the following quadrilaterals:

(i) Quadrilateral MORE


(ii) Quadrilateral PLAN

(iii) Parallelogram HEAR

(iv) Rectangle OKAY




To construct, a quadrilateral MORE.

Step of Construction:

(a) Draw a line segment.

(b) Construction and taking radius, draw an arc taking O as centre, which intersects at R.

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

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

It is the required quadrilateral MORE.


A Figure is Quadrilateral MORE


Given, ,

To construct, quadrilateral PLAN

Step of Construction:

(1) The sum of Quadrilateral angle is

(2) Draw in line and quadrilateral is below.


A Figure is Quadrilateral PLAN

(3) Draw an angle of at point L. As vertex A is 6.5 cm away from vertex L, cut a line segment LA of 6.5 cm.


A Draw an Angle of 75 Degree

(4) Again draw an angle of at point A.


A Draw an Angle of 110 Degree

(5) Draw an angle of at point P. this ray will meet the previously drawn ray from A at point N.


A Draw an Angle of 90 Degree

PLAN is required Quadrilateral.
