In the diagram, p1p2 and q1q2are the perpendicular bisectors of ab and bc, respectively. a1a2 and b1b2 are the angle bisectors of ∠a and ∠b, respectively. what is the center of the circumscribed circle of δabc?
see attachment below for picture/answer choices

We have to choose the correct answer for the center of the circumscribed circle of a triangle. The center of the circumscribed circle of a triangle is where the perpendicular bisectors of a triangle intersects. In this case P1P2 and Q1Q2 are perpendicular bisectors of sides AB and BC, respectively and they intersect at point P. S is the point where the angle bisectors intersect ( it is the center of the inscribed circle ). P.
