Question 1.
Construct the following quadrilaterals.
(i) Quadrilateral
DEAR
DE = 4 cm
EA = 5 cm
AR = 4.5 cm
āˆ E = 60Ā°
āˆ A = 90Ā°

(ii) Quadrilateral
TRUE
TR = 3.5 cm
RU = 3 cm
UE = 4 cm
āˆ R = 75Ā°
āˆ U= 120Ā°
Solution:
(i) Steps of construction:
I. Draw a line segment DE = 4 cm.
II. At E, draw \(\overrightarrow { EX } \) such that āˆ DEX = 60Ā°.
III. From \(\overrightarrow { EX } \), cut-off EA = 5 cm.
IV. At A, draw ray \(\overrightarrow { AY } \) such that āˆ EAY = 90Ā°.
V. From \(\overrightarrow { EY } \), cut-off AR = 4.5 cm.
VI. Join R and D.

I. Draw a line segment \(\overrightarrow { TR } \) =3.5 cm.
II. At R, draw a ray \(\overrightarrow { RX } \) such that āˆ TRX = 15Ā°.
III. From \(\overrightarrow { RX } \) , cut-off RU = 3 cm.
IV. At U, draw \(\overrightarrow { UY } \) such that āˆ RUY = 120Ā°
V From UY, cut-off \(\overrightarrow { UE } \) = 4 cm.
VI. Join E and T.
Thus, TRUE is the required quadrilateral.
