Therefore, the new position of point M (-2, 3) will become M’ (3, 2). 2. Find the co-ordinates of the points obtained on rotating the point given below through 90° about the origin in clockwise direction.Hence, 180 degree?). STEP 5: Remember that clockwise rotations are negative. So, when you move point Q to point T, you have moved it by 90 degrees clockwise (can you visualize angle QPT as a 90 degree angle?). Hence, you have moved point Q to point T by "negative" 90 degree. Hope that this helped.180° Rotation (Clock Wise and Counter Clock Wise) Once students understand the rules which they have to apply for rotation transformation, they can easily make rotation transformation of a figure.
