20. Given circle C with radius r and circle D with radius s, what is an appropriate first step when proving

circle C is similar to circle D?

O A. Transform circle C with a dilation that has center

Cand scale factors.

B. Transform circle C with a dilation that has center

C and scale factor r.

O C. Transform circle C with the translation that maps

point Conto point D.

OD. Transform circle C with the translation that maps

point onto point C.

A. Transform circle C with a dilation that has center  C and scale factor s.

Step-by-step explanation:

Given

Circle C

Circle D

Required

Map C to D

From the question, we can assume that:

This implies that options c and d are false because when an object is translated from one point to another, the size of the object remains unchanged.

To map C onto D,

1) C has to be dilated from its own center C

2) The scale of dilation will be equal to the radius of D (i.e. s)

Hence, (A) is correct

answer: 2/4
