Construct a square of side 4.8 cm and draw all its lines of symmetry .
उत्तर
Steps of Construction :
(i) Draw a line segment AB = 4. 8 cm.
(ii) At A and B, draw perpendiculars AX and BY
(iii) From AX and BY, cut off AD = BC= 4. 8 cm
(iv) Join DC. ABCD is the required square.
(v) Now cir aw perpendi cu I ar bi sectors of AB and AD.
(vi) Also join the diagonals AC and BD.
The perpendicular bisectors and the diagonals are the lines of symmetry
