A line that is perpendicular to the segment of a plane and passes through the midpoint.
all three perpendicular bisectors elongate to meet at the incenter of the triangle.

Since the intersection of the perpendicular bisectors of a triangle is the center of the inscribed circle (we call it the centroid of a triangle), the answer is no.
Equilateral triangles have 3 perpendicular bisectors
No, they are just bisectors. The angle between them is not (usually) the 90o required to be perpendicular.
True, the diagonals of a rhombus are perpendicular bisectors of one another.

If the diagonals are congruent and are perpendicular bisectors of each other then the parallelogram is a square. If the diagonals are not congruent but are perpendicular bisectors of each other then the figure would be a rhombus.

The perpendicular bisectors only intersect on the triangle when it is an isosceles right triangle.
