which of the following is not a property of rectangles?

answer attempt 1 out of 2
opposite sides are parallel and congruent
diagonals bisect eachother
diagonals are congruent
one pair of sides not congruent
submit answer

Explanation:

A rectangle is a quadrilateral with all right angles. Its key properties include: opposite sides are parallel and congruent; diagonals bisect each other and are congruent. The statement that one pair of sides is not congruent directly contradicts the definition of a rectangle, as both pairs of opposite sides must be congruent.

Answer:

C. Diagonals are congruent, D. One pair of sides not congruent

Wait, correction: The non-property options are:
C. Diagonals are congruent is a property, so the incorrect ones are:
D. One pair of sides not congruent, C. Diagonals are congruent is a property, so the correct non-properties are:

Correct Answer:

C. Diagonals are congruent is a property, so the non-properties are:
D. One pair of sides not congruent, and C is a property, so the answer is:

Final Answer:

C. Diagonals are congruent (is a property, so not the answer), D. One pair of sides not congruent (is not a property)

Wait, re-clarifying:
The question asks which is NOT a property of rectangles.

1. opposite sides are parallel and congruent: This is a property of rectangles.
2. Diagonals bisect each other: This is a property of rectangles.
3. Diagonals are congruent: This is a property of rectangles.
4. One pair of sides not congruent: This is NOT a property of rectangles, as rectangles have both pairs of opposite sides congruent.

Correct Answer:

D. One pair of sides not congruent
