Question

Rhombus CDEF with vertices C(-5, 5), D(-1,7), E(-3, 3), and F(-7, 1): 270° counterclockwise

Answer 1

The required coordinates of the pre image are C'(-5, -5), D' (7, 1), E' (3, 3) and F' (1, 7)

Rotation of coordinates

Rotation is a way of changing the position of an object on an xy plane.

When a coordinate point (x, y )is rotated 270 degrees counterclockwise, the resulting coordinate point will be (y,-x)

The x-coordinate is negated and then swapped.

Given the coordinates of a Rhombus CDEF with vertices C(-5, 5), D(-1,7), E(-3, 3), and F(-7, 1), the resulting coordinate points will be;

C(-5, 5) = C'(-5, -5)

D(-1,7) = D' (7, 1)

E(-3, 3) = E' (3, 3) and

F(-7, 1) = F' (1, 7)

Hence the required coordinates of the pre image are C'(-5, -5), D' (7, 1), E' (3, 3) and F' (1, 7)
