Answer:
Circumcenter
Step-by-step explanation:
Triangle is a three-dimensional figure which has three sides, three vertices and three angles.

Circumcenter lies outside the triangle in case of an obtuse angled triangle, at the midpoint of the hypotenuse in case of the right triangle and inside the triangle in case of an acute angled triangle.
