Answer:
A. an isosceles trapezoid
Step-by-step explanation:
We have been given a statement. We are asked to choose the expression that describes the given statement.
Statement: The diagonals of a quadrilateral are congruent but DO NOT bisect each other.
We know that diagonals of rectangle are congruent because opposite sides of rectangle are equal. We also know that diagonals of rectangle bisect each other.
By the properties of an isosceles trapezoid, the diagonals of an isosceles trapezoid are congruent, but they do not bisect each other.
Therefore, the required quadrilateral is an isosceles trapezoid and option A is the correct choice.
