Answer:
I don't use Geogebra, but the following procedure should work.
Step-by-step explanation:
Construct a circle A with point B on the circumference.
- Use the POINT and SEGMENT TOOLS to create a circle with centre B and radius BA.
- Use the POINT tool to mark points D and E where the circles intersect.
- Use the SEGMENT tool to draw segments from C to D, C to E, and D to E.
You have just created equilateral ∆CDE inscribed in circle A.
