Three Touching Circles

**Acorn** · 23 October 2018, 03:56 PM

How easy can you make it for others to draw three 200px circles of red, green and blue colour so that they just touch each other?

The Challenge is to use no other shapes. Snapping is allowed.

Keith, I like the use of the Nudge setting.

I do believe there is a simpler approach though your does work.

… and why not? We have magnetic snap. Where is the problem? I don't see it.
One Circle – two copies. Nothing else.

If I'm wrong pls correct me, it's maybe the older I've.

If I drag and drop a duplicate circle approximately between the top two circles, then I can select the bottom circle and move it until the snap guidelines appear when centered.
