if yes then keep the tracing paper on the triangle and draw over it. be4 moving the paper place a dot over (0,0) and turn the paper 90 degrees anti clockwise. plce the dot on the tracing paper above (0,0) and redraw the diagram.
hope this helped.

How do you know where to draw the rotation in this case? I drew mine in quadrant 3, idk why..
If anyone can share some insight, that would be really helpful!!! ???

try this method...join the center with all the three points..
next, for each line (joining the point and the center) make a perpendicular line towards the left...(because its anticlockwise)
after uve made the respective image lines...mesaure the the length of the object line and mark a point on the image line of the exact same length..

ur supposed 2 get it!!
anyways try this. measure how far a certain point is from ur center of rotation eg A
then use a set square and plot a point the same distance away from center of rotation anticlockwise. and copy the rest of the points.
