Question

construct a quadrilateral ABCD where AB=BC= 3 cm, AD=CD= 5cm and angle B = 120 degree. Measure the length of the diagonals of the quadrilateral.​

Answer 1

The given details are AB = BC = 3 cm, AD = CD = 5 cm and ∠B = 120°. Steps to construct a quadrilateral: Step 1- Draw a line AB = 3cm Step 2- Construct and angle of 120o at B. Step 3- Cut an arc of radius 3cm with B as the center to mark that point as C. Step 4- Cut an arc of radius 5cm with C as the center to mark that point as D. Step 5- Cut an arc of radius 5cm with A as the center to intersect at point D. Step 6- Now join BC, CD and DA.
