## Sunshine447 3 years ago Which statement best compares a square and a rhombus? B, right?

1. Sunshine447

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.

2. apple_pi

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

3. Sunshine447

Yay! Thanks!

4. Sunshine447

@apple_pi can you help me with one more?

5. apple_pi

Sure...

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?

7. apple_pi

Ahh, let me draw

8. Sunshine447

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

9. apple_pi

Ok, so like this?

10. Sunshine447

yes... how did you do that?

11. apple_pi

12. Sunshine447

and AD is the altitude right?

13. apple_pi

Yep

14. Sunshine447

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

15. apple_pi

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

16. Sunshine447

yeah

17. apple_pi

Wait, i'm thinking

18. Sunshine447

k

19. apple_pi

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

20. apple_pi

21. Sunshine447

okay

22. apple_pi

23. apple_pi

24. Sunshine447

right

25. apple_pi

now make AD the subject in both of these

26. Sunshine447

how?

27. apple_pi

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

28. Sunshine447

okay

29. apple_pi

hmm, I just lost it

30. apple_pi

@lgbasallote any idea?

31. apple_pi

@Callisto ?

32. apple_pi

Am I on the right track here?

33. Callisto

Blah... @Sunshine447 Post close the question and start a new post for a new question. Thanks!
