Which statements about a square are always true?

- 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.
