Construct a rectangle ABCD in which AB = 7 cm and BC = 5 cm. Draw all its line(s) of symmetry.
Answer
Steps:
Draw AB = 7 cm.
At B, construct angle XBA = 90°. From BX cut BC = 5cm.
Taking C as centre, draw an arc of radius 7 cm (= AB) and taking A as centre, draw one more arc of radius 5 cm (= BC). Let these two arcs intersect at point D.
Join AD and CD.
Hence, ABCD is the required rectangle.
