Construct a quadrilateral ABCD given that CD = 7cm, AD = 5 cm, ∠A =1

1.	Construct a quadrilateral ABCD given that CD = 7cm, AD = 5 cm, ∠A =120⁰,∠B =75⁰ and ∠C=135⁰.
Answer» Answer: Draw a line segment AB=4.5cm ⇒ Take B as center and draw an angle of 60 o . ⇒ Cut off BC=5.5cm ⇒ Take A as with radius 4.8cm and draw an arc. ⇒ Take C as with radius 5cm and draw an arc, which cuts off PREVIOUS arc at POINT D ⇒ Join CD and AD.

Answer:

Draw a line segment AB=4.5cm

⇒ Take B as center and draw an angle of 60

⇒ Cut off BC=5.5cm

⇒ Take A as with radius 4.8cm and draw an arc.

⇒ Take C as with radius 5cm and draw an arc, which cuts off PREVIOUS arc at POINT D

⇒ Join CD and AD.
