Question

Construct a trapezium ABCD, in which $AD\parallel BC$, AD = 3 cm, AB = 2.5 cm, BC = 5 cm, and CD = 2.8 cm.

Answer 1

Concept :
In trapezium ABCD, $AD\parallel BC$. A trapezium can be divided into a parallelogram ABED and a triangle DEC.
AB = DE [Opposite sides of a parallelogram]

Steps of construction :

1. Construct a line segment of BC.
2. Divide BC into two parts as BE = 3 cm and EC = 2 cm.
3. Taking B as the centre, draw an arc of 2.5 cm.
4. Taking E as the centre, draw an arc of 2.5 cm which intersects the previous arc at point A.
5. Taking A as the center, draw an arc of 3 cm.
6. Taking E as the center, draw an arc of 2.5 cm which intersects the previous arc at point D.
7. Join AD and CD.
8. ABCD is your required trapezium.
