The correct choices for the two reflex angles are:
D) K
F) O
A reflex angle is an angle greater than 180 degrees and less than 360 degrees.
In a heptagon (a polygon with seven sides), two reflex angles are formed by selecting two non-adjacent vertices.
In this case, the two reflex angles are formed by selecting two non-adjacent vertices of the heptagon.
So, the correct choices for the two reflex angles are:
D) K
F) O
