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.
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
@apple_pi can you help me with one more?
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?
Ahh, let me draw
I know what an altitude is, but this one I just don't get at all...
yes... how did you do that?
and AD is the altitude right?
Ahhhh I used that program a lot... now it's photoshop, flash, and premiere pro for me haha... anyways.......
Do you get that AD splits ∆ABC into two similar triangles which are similar to the large triangle?
Wait, i'm thinking
Ok, so then AB/BC = BD/AD right?
So then AB/41 = 25/AD
Similarly, AC/BC = DC/AD right?
AC/41 = 16/AD
now make AD the subject in both of these
for the first one, AD = 16*41/AC
hmm, I just lost it
@lgbasallote any idea?
Am I on the right track here?
Blah... @Sunshine447 Post close the question and start a new post for a new question. Thanks!
