To rotate a point 180 degrees about the origin, you change the signs of the coordinates of that point.
If a rectangle has a vertex T with coordinates (x, y), then after a 180-degree rotation about the origin, the new coordinates \( T'' \) will be:
\[ T'' = (-x, -y) \]
If you provide the specific coordinates of point T from rectangle MATH, I can give you the exact coordinates for \( T'' \).
