a
To graph: The coordinates of P’, Q’and R’
a

Explanation of Solution
Given: is reflection of
Graph:
Interpretation: Since the reflection is taking place across y axis, therefore, the x coordinate will be equal distance from the y-axis on the other side. Therefore, Coordinates of will be
will be
and
will be
b
To prove: The congruency of with respect to
b

Explanation of Solution
Given: The, graph is given with
Proof:
As is the reflection of
Therefore, it would be equal in shape and size, therefore
