Question

7. A point A(-4,6) is reflected about x-axis to point B. Point B is then rotated through 180° about the origin
in clockwise direction to point C. Find the coordinates of points B and C.


8. The smallest angle through which a geometrical figure has to be rotated about a point to coincide with
its original position is 72º. Find the order of rotational symmetry of the figure.
​

Answer 1

Answer:

Ans 7.When the coordinate(-4,6) is reflected about x axis a new coordinate B(-4,-6) is formed. After that when B is rotated a new coordinate C(4,6) will form. ☺
