Question 18 Every rectangle is a square True or False

False Every rectangle is NOTa square (Yes, every square is a rectangle – Rectangles need 4 – 90 o and parallel sides; however, to be a square all sides need to be congruent) Question 18 - Answer

Question 23 A trapezoid can be a parallelogram! True or False?

False A trapezoid can never be a parallelogram… Question 23 - Answer because a trapezoid has one pair of parallel sides and a parallelogram has 2 pair of parallel sides.
