Answer:
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.
