Since a Rotation of a point through 180°, about the origin when a point a(h, k) is rotated about the origin through 180° in anticlockwise or clockwise direction.
then, By the rule of 180 degree rotation;
so, it takes the new position i.e,
Therefore, both the x and y coordinates of the point on δa'b'c' have opposite signs from the corresponding points on δabc.
