Yes, an isosceles trapezoid is one example.
A trapezoid is defined as a four-sided figure (quadrilateral) with at least one pair of parallel sides. The other pair of sides can be either parallel or non-parallel, and they are not necessarily perpendicular. In some cases, a trapezoid may have perpendicular sides, but this is not a requirement for its classification.
Zero
A trapezoid has one pair of parallel sides, which are its bases. The other two sides, called the legs, are not parallel and can be either perpendicular or slanted, depending on the specific type of trapezoid. In summary, a trapezoid has one pair of parallel lines and zero perpendicular lines by definition.
None but it has end sides of equal lengths
trapezoid
It doesn't need any in order to be a trapezoid. It can have a max of two pairs of perpendicular sides.
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.

A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
