    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

    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?

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

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

    So then AB/41 = 25/AD
