Question
Use graph paper for this question. (Take 2 cm = 1 unit along both x and y axis.) Plot the points O ( 0, 0 ), A( - 4, 4 ), B ( - 3, 0 ) and C ( 0, - 3 )
(i) Reflect points A and B on the y-axis and name them A’ and B’ respectively. Write down their coordinates.
(ii) Name the figure OABCB’A’.
(iii) State the line of symmetry of this figure
Solution
( i)
A' = ( 4, 4 ) and B' = ( 3, 0 )
( ii ) The figure is an arrow head.
( ii ) The y-axis is the line of symmetry of figure OABCB'A'.
