Question

Which statement best compares a square and a rhombus?

B, right?

Answer 1

A rhombus has all angles equal to 90° but a square has opposite angles equal.

A rhombus has diagonals which are unequal but a square has diagonals which are equal.

A rhombus has equal diagonals but a square has unequal diagonals.

A rhombus has non perpendicular diagonals but a square has perpendicular diagonal.

Answer 2

The first one is definitely not, a rhombus's angles are not all 90°
The last one is wrong, because a rhombus has perpendicular diagonals.
The third one is wrong, because a square certainly has equal diagonals.

So yes, it is B.

Just think over the properties of a rhombus and square

Answer 3

Yay! Thanks!

Answer 4

@apple_pi can you help me with one more?

Answer 5

Sure...

Answer 6

When an altitude is drawn to the hypotenuse of a right triangle, the lengths of the segments of the hypotenuse are 16 and 25. What is the length of the altitude?

Answer 7

Ahh, let me draw

Answer 8

I know what an altitude is, but this one I just don't get at all...

Answer 9

Ok, so like this?

Answer 10

yes... how did you do that?

Answer 11

Adobe Illustrator

Answer 12

and AD is the altitude right?

Answer 13

Yep

Answer 14

Ahhhh I used that program a lot... now it's photoshop, flash, and premiere pro for me haha... anyways.......

Answer 15

Do you get that AD splits ∆ABC into two similar triangles which are similar to the large triangle?

Answer 16

yeah

Answer 17

Wait, i'm thinking

Answer 18

k

Answer 19

Ok, so then AB/BC = BD/AD right?

Answer 20

So then AB/41 = 25/AD

Answer 21

okay

Answer 22

Similarly, AC/BC = DC/AD right?

Answer 23

AC/41 = 16/AD

Answer 24

right

Answer 25

now make AD the subject in both of these

Answer 26

how?

Answer 27

for the first one, AD = 16*41/AC

Answer 28

okay

Answer 29

hmm, I just lost it

Answer 30
