## NCERT Solutions for Class 8 Maths Practical Geometry

###### 1. Construct the following quadrilaterals:

MO = 6 cm, OR = 4.5 cm,

M = O = R =

PL = 4 cm, LA = 6.5 cm,

P = A = N =

(iii) Parallelogram HEAR

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

(iv) Rectangle OKAY

OK = 7 cm, KA = 5 cm

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

M = O = R =

###### 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.

(b) Construct angle of  at P and produce the side PN.

(c) Construct angle of  at L and with L as centre, draw an arc of radius 6 cm, which intersects at A.

(d) Construct A =  at A and produce the side AN which intersects PN at N.

It is the required quadrilateral PLAN.

###### (iii)Given:  HE = 5 cm, EA = 6 cm,

R =

To construct: A parallelogram HEAR.

To findH =

[ Sum of adjacent angle of gm is ]

Steps of construction:

(a) Draw a line segment HE = 5 cm.

(b) Construct H =  and draw an arc of radius 6 cm with centre H. It intersects AR at R.

(c) Join RH.

(d) Draw R = E = and draw an arc of radius 6 cm with E as a centre which intersects RA at A.

(e) Join RA

It is the required parallelogram HEAR.

(iv) Given:  OK = 7 cm, KA = 5 cm

To construct: A rectangle OKAY.
