Mathematics
In the given figure, AP is bisector of angle A of △ ABC and DP is perpendicular bisector of side AB, then :
P is incenter of △ ABC
P is circumcenter of △ ABC
PB bisects angle B
none of these
Answer
The incenter of a triangle is the intersection point of all the three interior angle bisectors of the triangle.
The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of triangle intersect.
Since,
In the given figure, P is intersection of an angle bisector and perpendicular bisector of a side.
Hence, Option 4 is the correct option.
