a rhombus is something like this but mine isnt so accurate.

Answer 12

Still a parallelogram.

Answer 13

All rhombuses are parallelograms, but not all parallelograms are rhombuses

Answer 14

i get what you say but when i see my picture i dont ?

Answer 15

You don't what?

Answer 16

like this or not?

Answer 17

Both of these are parallelograms, only the top one is a (poorly drawn) rhombus.

Answer 18

i just did that. except mine isnt good

Answer 19

As I asked a dozen comments ago, when figuring out which shapes are what, you have to know the definitions.

WHAT IS THE DEFINITION OF A RHOMBUS?

Answer 20

>>> "a Rhombus is a parallelogram with opposite equal acute and obtuse angles and four equal sides" NOT TRUE

Answer 21

As @qweqwe123123123123111 says, go back to the definitions of rhombus and square. That is the key to the answer here.

Answer 22

a Rhombus is a parallelogram with all sides congruent right?

Answer 23

@Danny_Boy left for another problem:

Answer 25

A rectangle is a four-sided shape where every angle is a right angle (90°).

Answer 26

Sort of.

A rhombus is a 4 sided figure with 4 EQUAL LENGTH SIDES.

Answer 27

" Rhombus is a parallelogram with all sides congruent right? CORRECT

Answer 28

Equally correct: A rhombus is a 4 sided figure with 4 EQUAL LENGTH SIDES.

Answer 29

Definition of Square, please?

Answer 30

oh ok then so a square is a plane figure with four equal straight sides and four right angles.

Answer 31

So are all squares rhombuses?

Are all rhombuses squares?

Answer 32

1. yes
2. no

Answer 33

Correct!!! :-)

Bonus: all squares and all parallelograms are quadrilaterals. :-)

Answer 34

haha yay i got it so its true?

Answer 35

@Danny_Boy missed out on this valuable lesson.

Answer 36

Yes, it's true.

If a quadrilateral is a square, then it is a square by definition

If a figure is a square, then it is always a rhombus.

Answer 37
