3 and they meet in a single point called Circumcentre
Equilateral triangles have 3 perpendicular bisectors
Exactly one. No more, no less.
In a plane, there are infinitely many lines that can serve as perpendicular bisectors of a given segment. The unique perpendicular bisector of a segment is a specific line that divides the segment into two equal parts at a right angle. However, any line parallel to this unique bisector, at any distance, can also be considered a perpendicular bisector if it intersects the segment at its midpoint. Thus, while the unique perpendicular bisector exists, an infinite number of lines can be drawn parallel to it.
If it's a right triangle, then one.There is no other way to have a perpendicular angle in a triangle without it being 90 degrees, or right.

An equilateral triangle doesn't have any perpendicular sides on it.
if the triangle is a right angle it has 2 perpendicular line segments.
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
