Describe a circle tangent to two given circles, one of the points of contact is given.

OpenStudy (astrophysics):

This is what I'm trying to do sort of lol, but it looks so damn weird. https://puu.sh/skVhC/89c17a765c.png

OpenStudy (astrophysics):

As I want the radius drawn from the point of tangency to be perpendicular for all circles, but I don't think that's possible haha

OpenStudy (astrophysics):

uh wait

OpenStudy (astrophysics):

|dw:1479355463375:dw| oh baby that should do the trick, I don't even need that line m heh

OpenStudy (astrophysics):

I think..mhmm, these problems are pretty tough >.<

What is the exact problem ?

OpenStudy (astrophysics):

"Describe a circle tangent to two given circles, one of the points of contact is given."

OpenStudy (astrophysics):

Yup, that's how all the problems are, you get one little statement and you write 3 pages of proof figuring out what the heck to do.

ganeshie8 (ganeshie8):

Basically they gave us two circles in a plane and we have to find a circle that is tangent to both the circles ?

OpenStudy (astrophysics):

If I drew a secant for the circle notice how it will be a secant for all of the circles

OpenStudy (astrophysics):

Yes

ganeshie8 (ganeshie8):

They gave us one of the contact points also

OpenStudy (astrophysics):

Yup so I can say like |dw:1479355861096:dw| that point A is given

ganeshie8 (ganeshie8):

|dw:1479355855700:dw|

OpenStudy (astrophysics):

Exactly, that's the plan :p

OpenStudy (astrophysics):

So you think that's fine assuming that huge shaded in black circle is the given point?

ganeshie8 (ganeshie8):

Is this going to be a messy coordinate geometry proof ? If so, we have to assume the centers of those two circles are also given..
