No but it does have a perpendicular line of symmetry.
Not normally but as an isosceles right angle triangle it will have perpendicular lines that meet at 90 degrees.
None but its apex is perpendicular to its base
The perpendicular bisectors only intersect on the triangle when it is an isosceles right triangle.
Yes.
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.
The only requirement for an isosceles triangle is that two sides be the same length and one be different. It is possible for an isosceles triangle to have two perpendicular legs. It would be right and isosceles.
If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
No but it does have a perpendicular line of symmetry.
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
Not normally but as an isosceles right angle triangle it will have perpendicular lines that meet at 90 degrees.

None
Yes.
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
thank goodness for my math teacher, norm! he said only in an isosceles triangle. The bisector of the vertex angle of an isosceles triangle is perpendicular to the base! =)
