    1. A regular polygon consists of isosceles triangles. The base of one triangle is one side of the polygon.

    2. The value of one interior angle equals the sum of the base angles of one of the isosceles triangles. Thus the center angle must be 50

    3. The center angle must be a divisor of 360. Since 50 is not a divisor of 360 the solution of K. must be wrong.
