Circle 1 is centered at (5, 8) and has a radius of 8 cm
Circle 2 is centered at (1, −2) and has a radius of 4 cm
To transform circle 1 to circle 2 ⇒⇒ we need to transform (5,8) to (1,-2)
the transformation rule (x-4 , y-10)
because 5-1 = 4 and 8-(-2) = 10
while circle 1 has a radius = 8 and the circle 2 has a radius = 4 cm
So, the dilation factor = 4/8 = 0.5
The correct answer is :
The
circles are similar because you can translate Circle 1 using the
transformation rule ( x-4 , y-10) and then dilate it using a scale factor
of 0.5
