Which sequence of transformations applied to shape i proves that shape i is similar to shape ii?
a.
a reflection across the y-axis, and then a dilation by a scale factor of 0.5
b.
a translation 5 units right and 1 unit up, and then a dilation by a scale factor of 0.5
c.
a 90° clockwise rotation about the origin, and then a dilation by a scale factor of 0.5
d.
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 0.5

C. a 90 degree clockwise rotation about the origin, and then a dilation by a scale factor of 0.5

Step-by-step explanation:

C.  

a 90° clockwise rotation about the origin, and then a dilation by a scale factor of 0.5

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size .

The transformation that happened here is -

A 90° clockwise rotation about the origin, and then a dilation by a scale factor of 0.5.

55 degrees because 55+55=110 degrees
