Ответ:
Option A.
Step-by-step explanation:
Biconditional statement : If both a conditional statement and its converse statement is true then it known as a bi-conditional statement.
Statement 1: A shape is a rectangle if and only if the shape has exactly four sides and four right angles. It is a biconditional statement because if the shape has exactly four sides and four right angles, then it must be a square or a rectangles and square is a special case of rectangle.
Statement 2: A shape is a trapezoid if and only if the shape has a pair of parallel sides.
If a shape has a pair of parallel sides then it can be a parallelogram.
Statement 3: A shape is a triangle if and only if the shape has three sides and three acute angles.
If a shape has three sides and three acute angles then it show an acute triangle.
Statement 4: A shape is a square if and only if the shape has exactly four congruent sides.
If a shape has exactly four congruent sides then it can also be rhombus.
So, the statements 2, 3 and 4 are not biconditional statements.
Therefore, the correct option is A.
