Hey, I just need assistence in Geometry (not my best subject). Any help is much appreciated, thanks so much!

1. Circle 1 has center (-4,5) and a radius of 6cm. Circle 2 has (2,-3) and a radius of 9cm. What transformations can be applied to circle 1 to prove that the circles are similar? Enter your scale factor as a fraction in simplest form.

- The circles are similiar because the transformation rule ( , ) can be applied to circle 1 and then dialate it using a scale factor of __?

2. Why is circle 1 similar to circle 2?

Circle 1: center (2,3) and radius 4

Circle 2: center (2,3) and radius 12

Options: Circle 2 is dialation of Circle 1 with a scale factor of 8, Circle 2 is a dialtion of Circle 1 with a scale factor of 3, Circle 1 and Circle 2 have the same center, or Circle 1 and Circle 2 are reflections of each other?

3. Which transformations can be used to show that Circle P is similar to Circle Q. Choose all that apply.

Options: Circle Q is a translation of Circle P 6 units left, Circle Q is a dilation of Circle P with a SF of 7, Circle P is a dialation of Circle Q with a scale factor of 24, and Circle Q is a translation of Circle P 6 units up.

4. According to these three facts, which statements are true? Select each correct answer.

*Circle M has center (1,10) and radius 12

*Circle N is a translation of Circle M, 1 unit left

*Circle N is a dialation of Circle M with a scale factor of 3

Options: Circle N and Circle M have equal diameters, the radius of Circle N is 12, the center of Circle N is (0,10), and Circle N and Circle M are similar.

&5. Suppose x is any positive number.

Circle 1: center (0,0) and radius 2x

Circle 2: center (0,0) and radius 10x

Why is Circle 1 similar to Circle 2?

Circle 2 is a dialation of Circle 1 with a SF of 0.2, Circle 1 and Circle 2 have equal areas, both circles have congruent diameters,  or Circle 2 is a dialation of Circle 1 with a scale factor of 5?

Come on guest, I always get upset when people do this.

You are meant to be using us to help you learn not to do all your homework for you!!
