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.
In an isosceles triangle, one of the medians is perpendicular to the opposite side of that triangle. In an equilateral triangle, all three medians are perpendicular to the sides of that triangle.
If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
Not normally but as an isosceles right angle triangle it will have perpendicular lines that meet at 90 degrees.
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.
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. The bisector of one angle of a triangle is the perpendicular bisector of theopposite side if the bisected angle is the vertex angle of an isosceles triangle,or any angle of an equilateral triangle.
