The inclusive definition of trapezoid would classify rectangles and squares as isosceles trapezoids. An Isosceles trapezoid has congruent base angles and at least one pair of parallel sides. Rectangles and squares fit these more restrictive criteria. All parallelograms are trapezoids but all parallelograms do not fit the more restrictive criteria of an isosceles trapezoid.

According to the website below, when using the inclusive definition of a trapezoid, an isosceles trapeziod is still defined as a "strict" trapezoid (exclusive definition) with congruent legs. Therefore squares and rectangles would not be included. Does that agree with the CCSS definition?
