Its a picture, id say of intersecting circles ... what is it you are trying to do with it?

anonymous · Answer

Oh I'm sorry I forgot to include the question!

anonymous · Answer

Prove that the two circles shown below are similar.

amistre64 · Answer

oh, we would need to know how your material defines similarity.

anonymous · Answer

Okay, can you explain how I would do that?  I didn't pay attention in class and I'm really regretting it know lol

amistre64 · Answer

i dont have your material, so i wouldnt know how they define it.  Your grade is based on what your material gives you.

amistre64 · Answer

an idea tho, is to move both so that they are centered at the origin, and then you can dilate one into the other.

anonymous · Answer

So, (an idea) of how they would be similar is that if the enlarge the smaller one 'x' times it would be the same as the larger one?

amistre64 · Answer

thats the idea yes.  how your material covers it tho, i havent a clue about.

but impretty sure it follows that process.

amistre64 · Answer

we can also determine a center of dilation if we dont want to move the circles.

amistre64 · Answer

i think its easier to move them tho

amistre64 · Answer

the radius and circumference are linear measures.

radius y = 3  
radius x = 2(3)

circumference x = 2(3)pi = 6pi
circumference y = 2[2(3)]pi = 2(6) pi

they have a common among corresponding sides.  but im not sure how well this conforms to your material.
