None but it has end sides of equal lengths
Two of the end sides.
What kind of isosceles? A isosceles triangle has 3 sides, while a isosceles trapezoid has 4 sides. Hope i helped:)
It has one pair
A trapezoid typically has two parallel sides and two non-parallel sides. Depending on its specific type, such as a right trapezoid, it may have one or two perpendicular sides. In a right trapezoid, one of the non-parallel sides is perpendicular to the parallel sides, resulting in one pair of perpendicular sides.
Zero
Two of the end sides.
The two outer sides
It doesn't need any in order to be a trapezoid. It can have a max of two pairs of perpendicular sides.

If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
One pair
Normally none but in the form of an isosceles trapezoid its 2 non-parallel sides are of the same lengths.
