Dee says: "This shape has 4 sides and 2 pairs of parallel sides, so it must be a rectangle." Is she right?
Yes. Parallel sides always make a rectangle.Yes. Every four-sided shape is a rectangle.No. It leans, so it has no right angles.

Answer key · Set C
Always, Sometimes or Never?
1sometimes Some rectangles have four equal sides, and those are squares. Other rectangles have sides of different lengths.
21-C, 2-A, 3-B Every square has four right angles, a rhombus is a square only when its angles are right angles, and a triangle has only three sides.
3square Four equal sides and four right angles is a square.
4A Shape A leans, so it has no right angles. A square and a rectangle both have four right angles.
5square, rectangle A square and a rectangle have four right angles. The rhombus and the leaning parallelogram lean, so their angles are not right angles.
6True A rhombus is a parallelogram with four equal sides, so it has everything a parallelogram has.
7False This parallelogram has a long pair of sides and a short pair. Only a rhombus needs four equal sides.
8parallelogram All three have four sides and two pairs of parallel sides. A rectangle does not hold every rhombus, and a rhombus does not hold every rectangle.
9No. It leans, so it has no right angles. A parallelogram needs four right angles to be a rectangle. This one leans.
102 A parallelogram has two pairs of parallel sides.
11rectangle Four right angles makes it a rectangle, and sides that are not all equal means it is not a square.
