Exercise 4.1

1. Construct the following quadrilaterals.

(i) Quadrilateral ABCD

AB = $4.5$cm

BC = $5.5$cm

CD = 4 cm

AD = 6 cm

AC = 7 cm

Ans: Firstly, sketch a rough drawing of this quadrilateral as shown below.

(1) \[\Delta ABC\]can be constructed by drawing one arc with centre B and radius $4.5$cm and one arc with centre C and radius 7cm.


seo images

(2) Vertex D is 6 cm away from vertex A. Therefore, draw

an arc by taking A as centre and radius 6 cm.


seo images

(3) Draw an arc with centre C radius 4 cm, and the arc is cutting the previous arc at point

D. Join AD and CD.

ABCD is the required quadrilateral.

(ii) Quadrilateral JUMP

JU = \[3.5\]cm

UM = 4 cm

MP = 5 cm

PJ = $4.5$cm

PU = \[6.5\] cm

Ans: Firstly, sketch a rough drawing of this quadrilateral as shown below.


seo images

(1) \[\Delta JUP\] can be constructed by drawing one arc with centre P and radius $4.5$cm and one arc with centre U and radius \[3.5\]cm.


seo images

(2) Draw an arc with centre P and radius 5 cm and another arc with centre U and radius 4 cm. Let the point of intersection be M.

 Join the lines MP and MU.

JUMP is the required quadrilateral.

iii) Parallelogram MORE

OR = 6 cm

RE = $4.5$cm

EO = \[7.5\]cm

Ans: We know that opposite sides of a parallelogram are equal in length and also these are parallel to each other.


seo images

Hence, ME = OR, MO = ER

A rough sketch of this parallelogram can be drawn as follows.

(1)  \[\Delta EOR\] can be constructed by drawing one arc with centre O and radius \[7.5\]cm and one arc with centre R and radius \[4.5\]cm. And the intersection is point E

(2) Draw arc with centre O and radius $4.5 cm$ and another arc with centre E and radius  6 cm. These will intersect each other at point M.

(3) Join the lines ME and MO.

MORE is the required parallelogram.

(iv) Rhombus BEST

BE = $4.5$cm

ET = 6 cm

Ans: We know that all sides of a rhombus are of the same measure.

Hence, BE = ES = ST = TB.

 (Image will be Uploaded Soon)

A rough sketch of this rhombus can be drawn as follows.

(1) \[\Delta BET\]can be constructed by drawing arcs, each of radius of 4.5 cm with center as E, T.

(Image will be Uploaded Soon)

(2) Again draw arcs, each of radius of 4.5 cm with center as E, T below the triangle EBT, which will be intersecting each other at point S.

(Image will be Uploaded Soon)

(3) Join the lines SE and ST.

BEST is the required rhombus.
