Question

Construct a quadrilateral ABCD, given that AB = 5cm, BC = 4.5cm, angle A = 60°,angle B = 75°, and angle C = 85°.
​

Answer 1

Answer:

Steps of Construction:

(i) Construct AB = 5 cm.

(ii) At the point A, construct ∠A = 90 ⋅

(iii) At the point B, construct ∠B = 60 .

(iv) Taking B as centre and radius 4.2 cm cut off ∠B at C.

(vi) Taking A as centre and radius 3.5 cm cut off ∠A at D.

(vi) Now join CD.

Therefore, ABCD is the required quadrilateral

Answer 2

AB=5cm
BC=4.5
A=60
B=75
C=85
