Equilateral triangles have 3 perpendicular bisectors
Exactly one. No more, no less.
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.
None
Since there is no such word as "perpindicuar", it is difficult to be sure. A line segment can have only one perpendicular bisector.

Exactly one. No more, no less.
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.
