Yes. Imagine a right-angled triangle with one of its legs forming the base. Cut of the apex (the top angle) using a line parallel to the base. You will then have a trapezoid with a right angle. In fact, since a trapezoid contains a pair of parallel lines, it has two pairs of supplementary angles (add up to 180 deg). So a trapezoid cannot have only one right angle. If there is one, there must be 2 (or 4).
Add up the sides.
A trapezoid may either have no right angles or two right angles. It can have two right angles providing that the other two angles are acute and obtuse, respectively. The four interior angles must add up to 360 degreesNone normally but it is possible for a trapezoid to have 2 right angles, 1 obtuse angle and 1 acute angle that altogether add up to 360 degrees
360
A trapezoid can have up to two right, 90 degree angles for it still to be classified as a trapezoid.
