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.
Can have no pairs or one pair...
a trapezoid has 1 pair of parallel lines and a rectangle has 2 parallel lines
A trapezoid has one pair of parallel sides. They are opposite parallel lines of different lengths.
Yes, they can be. Here is an example to see how this is true. Construct two perpendicular lines AB and CD that intersect at a point O. Let AO = CO, BO = DO and AO ≠ BO, then ABDC forms an isosceles trapezoid. If the lines are not perpendicular, then also ABDC is an isosceles trapezoid and it has perpendicular diagonals.
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.
A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.

No, but it does have 1 pair of opposite parallel lines of different lengths
A shape that has two parallel lines and no perpendicular lines is a trapezoid, specifically an isosceles trapezoid. In this shape, one pair of opposite sides is parallel, while the other pair is not perpendicular to the parallel sides. This creates a unique geometry without right angles. Another example could be a parallelogram, which also has two pairs of parallel sides but does not necessarily have any perpendicular lines.
It can, but it need not.
A trapezoid has 1 pair of opposite parallel lines of different lengths
a pair of intersecting lines that are perpendicular
In a trapezoid, the pair of parallel lines are the bases of the trapezoid. These are the two opposite sides of the trapezoid that do not intersect.
A trapezoid has 2 parallel lines. It may or may not have perpendicular lines.
To prove that a quadrilateral is a right trapezoid, you need to show that it has one pair of parallel sides and one pair of right angles. This can be done by using the properties of parallel lines and perpendicular lines.
Lines that intersect at 90 degrees are perpendicular lines
