Question

Shape A can be transformed to shape B by a rotation 90° clockwise about (-1, 1) followed by a translation by vector

Answer 1

The values of a and b if the coordinate is rotated 90° clockwise is -1 and -1

Rotation of coordinates

The rotation is a transformation technique that changes the position of an object in an xy plane. If the coordinate (x, y) is rotated 90° clockwise, the resulting coordinate will be at (-y, x)

If the coordinate (-1, 1) is therefore rotated 90° clockwise about the origin, the resulting coordinate will be (-1, -1).

Comparing

a = -1 and b = -1

Hence the values of a and b if the coordinate is rotated 90° clockwise is -1 and -1
