Answer:


Explanation:
Given co-ordinates are

Part a
We will find the co-ordinate of ABC by translating 6 units to the right.
If any co-ordinate say
is translated
units to the right then co-ordinate of translated point
will be

Here we are translating 6 units to the right. So, our
is 6.
Now, co-ordinates after translating is

Part b
Now, we will find the co-ordinate of ABC after translating 6 units to the right with a rotation of 90°.
When any point say
is rotated 90° the new co-ordinate after rotation about the origin is
.
So, new co-ordinates are
