Answer: Angle bisector
The angle bisector is the line that cuts an angle in half. The three angle bisectors all intersect at the same point which is the incenter. The incenter is the center of the circle in which is largest possible, yet it's fully inside the triangle. No part of this circle is outside the triangle.
From here, it looks like all three sides of the right triangle are missing. I don't see any of them in the question.
<u>Supplementary:</u> N and M & N and I
Supplementary angles: A pair of angles whose sum is equal to 180°.
<u />
<u>Vertical:</u> M and I
Vertical angles: A pair of opposite angles that are made by two intersecting lines.
<u>Complimentary:</u> None
Complimentary angles: A pair of angles whose sum is equal to 90°.
Hope this helps! :D
