Question 3
Minh draws the Venn diagram below to show the relationships among trapezoids, isosceles trapezoids, parallelograms and rhombuses, but forgets the labels. Which set does the shaded region represent?
Convention used in this diagram: a trapezoid has at least one pair of parallel sides; an isosceles trapezoid has equal angles at each base (so rectangles are included).
