Exercise – 4.4
1. Construct the following quadrilaterals,
(i) Quadrilateral DEAR
DE = 4 cm
EA = 5 cm
AR = 4.5 cm
∠E = 60°
∠A = 90°
Solution –
Construction :
Step I – Draw DE = 4 cm.
Step II – Draw an angle of 60° at E.
Step III – Draw an arc with centre E and radius 5 cm to meet the angle line at A.
Step IV – Draw an angle of 90° at A and cut AR = 4.5 cm.
Step V – Join DR.
Thus, DEAR is the required quadrilateral.
(ii) Quadrilateral TRUE
TR = 3.5 cm
RU = 3 cm
UE = 4 cm
∠R = 75°
∠U = 120°
Solution –
Construction :
Step I – Draw TR = 3.5 cm
Step II – Draw an angle of 75° at R and cut RU = 3 cm.
Step III – Draw an angle of 120° at U and cut UE = 4.5 cm.
Step IV – Join TE.
Thus, TRUE is the required quadrilateral.
