Which statement describes a parallelogram that must be a square? a parallelogram with opposite sides that are congruent and diagonals that bisect the angles. a parallelogram with a right angle and opposites sides that are congruent. a parallelogram with a right angle and diagonals that bisect the angles. a parallelogram with all sides congruent.

Option 3 is correct.

Step-by-step explanation:

we have to select the statement which describe a parallelogram that must be square.

A square has all sides congruent and all angles 90°

In the third option

A parallelogram with a right angle and diagonals that bisect the angles.

Here, diagonals bisect the angles and all angles 90° which means base angles at the diagonals are of 45° both which makes the triangle isosceles and hence adjacent sides becomes equal.

which implies all sides becomes equal and all angles are congruent and of 90° . These properties are sufficient to call parallelogram a square.

Hence, Option 3 is correct.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
