Question 733916: Triangle ABC has vertices A(-2,3), B(-3,1), and C(-1,2). What are the vertices of A'B'C' after the triangle is rotated 180 degrees about the origin?

So far, what I have done was only state the type of coordinates that a rotation of 90 degrees and 180 degrees would make.
90 degrees rotation= (x,y) to (-y,x)
180 degrees rotation= (x,y) to (-x,-y)

Use your rule for 180 degree rotation on A,B,C to get:
A': (2,-3)
B': (3,-1)
C': (1,-2)
