Place bottle tops, top-side up, to make a shape. Record the co- ordinates of the corners of the shape. Place another set of bottle tops, teeth-side up, to show the image of the shape when it has been rotated 90° clockwise about the origin. Record these new co- ordinates. Compare the two sets of co-ordinate pairs. Show different shapes rotated 90° clockwise about the origin. Note the co-ordinates and investigate how the sets of co-ordinates are related. Now try rotations of other angles like 180° clockwise, 90° anticlockwise | BUSINESS MATHEMATICS HIGHER SECONDARY - SECOND YEAR Volume-1 Untouchability is a sin Untouchability is a crime Untouchability is inhuman TAMILNADU TEXTBOOK CORPORATION College Road Chennai - 600 006.
