Will mark BRAINLIEST!! — Point H is the circumcenter of triangle DEF. Which must be true? Check ALL that apply. See image.

Answer:A, C, FStep-by-step explanation:Definition: The circumcenter is  the center of the triangle's circumcircle - the circle that passes through all three of the triangle's vertices. If point H is the circumcenter of the triangle DEF, then the circumcircle passes through its vertices D, E and F (option A is true).Option B is false, the circumcircle doesn't pass through the points L, M and N. This option is true for inscribed circle, not for circumcircle.Option C is true, because HD and HE are the radii of the circumcircle.Option D is false. This option is true for inscribed circle, not for circumcircle.Option E is false. This option is true for inscribed circle, not for circumcircle.Option F is true, because both these angles are right angles.
