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 equilateral triangle: 3 In an isosceles triangle: 1 In a scalene triangle: 0
None.
two if the triangle has a right angle
None.
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 isosceles triangle has one line of symmetry, the perpendicular bisector of the base
Only one line of symmetry, it is the line that contains the median of the isosceles triangle (that passes through the vertex and perpendicular to the base).
None
An isosceles triangle has only 1 line of symmetry.
It varies depending on the angles and lines of the triangle.
