We explore a special geometric figure, consisting of a trapezoid, the Pepe trapezoid, and an ellipse. The trapezoid is non-rectangular and has integer side lengths. The ellipse is non-circular, inscribed into the trapezoid, and has integer semi-axis lengths. We prove that there are infinitely many non-similar isosceles Pepe trapezoids, right-angled Pepe trapezoids and Pepe trapezoids in the form of parallelogram.
