<u>ANSWER TO PART A</u>
The given triangle has vertices 
The mapping for rotation through  counterclockwise has the mapping
 counterclockwise has the mapping

Therefore



We plot all this point and connect them with straight lines.
ANSWER TO PART B
For a reflection across the y-axis we negate the x coordinates.
The mapping is

Therefore



We plot all this point and connect them with straight lines.
