Answer:
1. Quadrilateral, parallelogram, rectangle
2. Quadrilateral
3. Quadrilateral, trapezoid
4. Quadrilateral, parallelogram
Explanation:
Quadrilaterals are any closed polygons with 4 sides. All 4 questions are quadrilaterals. If they are not quadrilaterals, then none of the following will apply.
Parallelograms are quadrilaterals that have 2 pairs of opposite parallel sides.
Rectangles are quadrilaterals and parallelograms; their two pairs of opposite sides are congruent and parallel. The sides create a 90 degree angle.
Squares are quadrilaterals and parallelograms; all of the sides are congruent, two pairs have two parallel sides, and the sides are perpendicular, creating 90 degree angles.
Rhombi/Rhombuses are quadrilaterals and parallelograms; all of the sides are congruent and two pairs have two parallel sides, however they are not perpendicular and therefore don't create 90 degree angles.
Trapezoids have 1 pair of parallel sides, and the other pair is not parallel and sometimes can be congruent.
