Use the graph to complete the statement. O is the origin.
T<2,1> ο r(90°,O) : (4,-1)

After transformation the point will be (3, 5).
A rotational transformation can be done clockwise or anticlockwise to certain number of degrees. Rotational transformation does not alter the size and shape of the figure.
Rotating (4,-1) 90° anticlockwise centred at the origin yields the point (1, 4).
Then transforming the point (1, 4) two units to the right and 1 unit up results in the point (3, 5).
We can also rotate 90° clockwise that would result in some different point on this coordinate system.
Instead on a straight line we can also have some 2D figures like a triangle a rectangle etc.
