How to Link two given Circles Knowing the Radius of their Tangent Arcs

[@carolinelabbott2451]

This was very helpful as I have been wondering how best to link two circles exactly like this. So perfect timing this video was for me.
Thank you.

Thank you Arthur for your explanation! Great video! I'm new to geometry and I probably missed something, but where do you have r3 from and how to calculate it?

[@fookriver]

You make it look easy, thank you.

Excellent as always.

Should we know the distance between the line and the centre of the circle or do we draw it at any distance?

Is this magic?

Does this fall under excluding?

Bro: There's nothing we can do

Good luck!

So the circles of centres O3 and O4 have the radius of r3?

[@ArthurGeometry]

Yes

@@ArthurGeometry I had my finals and this specific question came out, I saw this video right before the exam, thank you

[@SH-um9lu]

I followed your steps. R1 = 3, R2 = 4, R3 = 8. Distance between initial circles = 15,4. Your construction results in 2 circles who are not ok. Only tangent to one circle !
