@AMQ

AMQ:

If I remember correctly, the formula for a 180 degree rotation is (x,y) -> (-x,-y). This means that to get our answer, you just need to change the values to negative. Note: If the value is already negative, you need to remember that two negatives make a positive.

Okay I got D :)

AMQ:

Hint: Since all of the points first move left on the x-axis and then move down on the y-axis, that means both the x-values and y-values for each point will be negative. Since we know the rule, we know that all the x-values and y-values will be turned to positive.

AMQ:

@trueangel12312 Correct. :D
