To find the new point (a',b') after rotating a point (a,b) counterclockwise about the origin by 180°, you can use the following formulas:
a' = -a
b' = -b
So if the original point is (x, y), the new point after rotating counterclockwise by 180° would be:
(-x, -y)
a' = -a
b' = -b
So if the original point is (x, y), the new point after rotating counterclockwise by 180° would be:
(-x, -y)
