Can have no pairs or one pair...
It doesn't need any in order to be a trapezoid. It can have a max of two pairs of perpendicular sides.
How many pairs of perpendicular sides does this figure have?
1 pair of parallel lines
10, A decagon has a maximum of five pairs of perpendicular lines, and a maximum of 5 parallel lines. however, this isn't in black and white it can have no pairs of line either perpendicular or parallel. know write the answer clearly
A trapezoid is a four sided quadrilateral that has only one pair of opposite parallel lines of different lengths.
Zero
It doesn't need any in order to be a trapezoid. It can have a max of two pairs of perpendicular sides.
A trapezoid has 2 parallel lines. It may or may not have perpendicular lines.
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.

One pair
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.
1 pair of parallel lines
Normally 1 pair
