In general, trapezoids do not have right angles. In fact, a trapezoid with a right angle is a special case, called a rectangle.
Each angle of a rectangle is a right angle. (90°)
Except for the special case of a rectangle, a parallelogram must have two acute angles.
A rectangle is a quadrilateral with 4 sides and 4 right angles. A square is a special form of rectangle, and it meets that criterion. But it is also equilateral, meaning its sides are all the same length (are all equal). It is a rectangle or a square. A square is a special type of rectangle with all sides having equal length. Here is a a nice chart showing the quadralaterals. http://content.answers.com/main/content/wp/en/f/f1/Quadrilateral_hierarchy.pngA quadrilateral where each angle is a right angle is known as an oblong.
A rectangle is defined as "a parallelogram with one right angle" A parallelogram is defined as "a quadrilateral with opposite sides equal and parallel" This makes a rectangle a sort of second-generation quadrilateral!
A parallelogram with a right angle is a rectangle.
Yes, a rectangle is a special kind of parallelogram - one that has a right angle. (You can prove that if it has one right angle all angles are right.)
A rectangle is not an angle.

A destroyed angle is called to as a rect-angle. It's a pun on the "wreck"tangle
Yes (or its special case, a square).

Yes, a rectangle can have one obtuse angle.
