the correct answers are: a. ) Point H is the center of the circle passing through points D, E and F. c. ) HE=HD
Based on the above, the correct choice S will be: Point H is the center of the circle passing through points D, E and F. HD = HE

Walkthrough A, C, F: Definition: The circumcircle is the center of the circumcircle of the triangle – the circle that passes through the three vertices of the triangle. If point H is the circumcircle center of triangle DEF, then the circumcircle passes through its vertices D, E, and F (option A is true). Option B is false, the circumscribed circle does not pass through the points L, M and N. This option is true for an inscribed circle, not for a circumscribed circle. Option C is true, because HD and HE are the radii of the circumcircle. Option D is wrong. This option is true for the inscribed circle, not for the circumscribed circle. Option E is wrong. This option is true for the inscribed circle, not for the circumscribed circle. Option F is true, because both angles are right angles.
