Question

Which statement is always true for a square, but not always true for a rhombus?

Answer 1

- Two angles are obtuse.
No.  There are no obtuse angles in a square.

- All sides are equal.
No.  It's true of squares AND rhombuses.

- Two or more angles are right angles.
Yes.  Always true for a square, sometimes true for a rhombus.

- More than two sides are parallel.
Confusing, so call it a 'no'. 
In both squares and rhombuses, every one of the four sides
is parallel to ONE other side.

Another important note:
Look at the statement that's true always for a square and sometimes for a rhombus:
"Two or more angles are right angles".
WHEN does a rhombus have right angles in it ?  Fasten your seat belt and hold on tight:
A square is a special kind of rhombus.  It's a rhombus that has right angles in it.
So a rhombus has right angles in it when it's a square.

Answer 2

two or more angles are right angles. Because a square always has 4 right angles to be a square, however a rhombus has no right angles because that would be a lame rhombus if its a square. Um yeah.
