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.
A triangle can have no parallel lines.
If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
In an equilateral triangle: 3 In an isosceles triangle: 1 In a scalene triangle: 0
None of the sides of any triangle are parallel. However, you can draw an infinite number of parallel lines inside any triangle.
None.

An isosceles triangle has no parallel sides but 2 of its 3 sides are equal in length
There are no parallel sides in a right angle triangle
An isosceles triangle has no parallel sides but it does have two equal sides
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.
An isosceles triangle has no parallel sides but it does have 2 sides of equal lengths
There are 0 parallel lines that a triangle has.
An isosceles triangle has only 1 line of symmetry.
how many sets of parallel lines are in a triangle
It varies depending on the angles and lines of the triangle.
A triangle can have no parallel lines.
