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.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
