Symmetry is of three types: Linear Symmetry, Point Symmetry and Rotational Symmetry.

In Rhombus, there are Two Lines of Symmetry

through 90 in anticlockwise direction. The new position of point M (h, k) will become M' (-k, h).

Find the new position of the A (2, 3) point when

rotated through 90 anticlockwise about the origin.

solution:

When rotated through 90 about the origin in anticlockwise

direction. The new position of the above point is:The new position of point A (2, 3) will become A' (-3,2)
