construct a trapezium ABCD where AB II CD, AB=6.5cmand CD=8.5 cm.Its other two sides AD=BC=3.5.
To draw the trapezium follow the follwing steps:
(1) Draw a line segment CD = 8.5 cm
(2) On line CD, cut-off CE = 2 cm
(3) With C as centre and radius 3.5 cm and with E as centre and radius 3.5 cm, draw two areas to cut each other at point B.
(4) With D as centre and radius 3.5 cm and B as centre radius 6.5 cm, draw two arcs to cut each other at point A.
(5) Join AD and AB
Thus, ABCD is the required trapezium.
