Level 5 - Solution not accepted #241

Explanation (sorry for the terms, my English is not native): Step 1: Draw a circle (center = A) going through C, It crosses segment AB on the point D --> ACD is equilateral Step 2: take the midpoint of AD (E) Step 3: segment [CE] is the mediatrice (?) of the ACD triangle, and the ACD triangle being equilateral, it is also perpendicular to its base (AD)

So segments (AB) an (EC) are perpendicular, thus matching the request

Not a valid solution for the exact same reason as I mentioned in #242 - additionally, you can see from the diagram that they're not perpendicular.
