This is a special case of a quadrilateral called a rectangle.
A square is a plane geometric figure having 4 equal sides and 4 right angles.
A rectangle has two right angles. In a rectangle, opposite sides are equal in length and all interior angles are 90 degrees. This geometric property distinguishes a rectangle from other shapes, such as squares or parallelograms, which may also have right angles but do not necessarily have exactly two right angles.
Well, honey, to draw a trapezoid with no right angles, you start by drawing two parallel lines of different lengths. Then you connect the ends of those lines with two slanted lines, making sure they're not perpendicular. Voila, you've got yourself a trapezoid with all angles different from 90 degrees. Now go show off your fancy geometric skills!
A rectangle has four right angles. Otherwise it wouldn't be a rectangle.

"How are straight angles different from right angles?" Is this a statement?
