Question

Use graph paper for this question (Take $2$ cm $=$ $1$ unit along both x and y axis). ABCD is a quadrilateral whose vertices are $A (2, 2), B (2, - 2), C (0, - 1)$ and $D (0, 1)$ . Name two points which are invariant under the above reflections.

Solution

Two points which are invariant under reflection are C and D because they lie on the y-axis
