Question

Which statement is true?

All parallelograms are rectangles.
All quadrilaterals are parallelograms.
All parallelograms are quadrilaterals.
All rectangles are squares.

Answer 1

What do you think the answer is?

Answer 2

I think that it is B or D, I'm not sure if all rectangles are squares or if all squares are rectangles.

Answer 3

All squares are rectangles. 4 sides, 4 right angles, 2 parallel pairs

Answer 4

But not all rectangles are squares. This is because some rectangles have sides that are not all equal. A characteristic of a square is all equal sides.

Answer 5

Some parallelograms consist of non 90 degree angles. All 90 degrees is a characteristic of rectangles.

Answer 6

Some quadrilaterals have sides that are not parallel, such as:

Answer 7

So "All quadrilaterals are parallelograms." is incorrect

Answer 8

What do you think the answer is now? :)

Answer 9

C?

Answer 10

Yes

Answer 11

Parallelograms come in two pairs of parallel sides. That is four sides total. The only requirement for a quadrilateral is four sides.
