Answer:
(a) Co-ordinate rule is and
(b) Co-ordinates of B' and C' are and
respectively.
Step-by-step explanation:
(a)
Here, the co-ordinates of A are translated to A'
.
For the co-ordinates A and A', and
So, x value of A has shifted to right by 6 units and y value of A has shifted 8 units down.
Hence, the co-ordinate rule that maps ΔABC onto ΔA'B'C' is:
and
.
(b)
Using the co-ordinate rule, we can find the co-ordinates of B' and C'.
For B, and
.
So, of B' is
And, of B' is
.
Therefore, co-ordinates of B' are .
For C, and
.
So, of C' is
And, of C' is
.
Therefore, co-ordinates of C' are .
