, []Adding circles to a triangle / It is good to explore with freehand.(GC World : Various Problems ,What will occur when something is added?)
Let's draw a triangle.
And let's add three circles with diameters that are the three sides of a triangle respectively.
What will occur?
I think that it is good to try this kind of problems on the paper.
"How about in the figure which I drew?"
"What must it become?"
It may be appropriate to test such things before, and then to compare the result of DGS.
