Question

which statement is true? a trapezoid has one pair of parallel sides. a square may not have 4 square corners. a rectangle may not have two pairs of parallel sides. a parallelogram has exactly 2 angles.

Explanation:

Step1: Analyze each option

• Option A: A trapezoid is defined as a quadrilateral with one pair of parallel sides.
• Option B: A square is a quadrilateral with four right (square) corners. So, the statement "A square may not have 4 square corners" is false.
• Option C: A rectangle is a parallelogram, and by the definition of a parallelogram, it has two pairs of parallel sides. So, the statement "A rectangle may not have two pairs of parallel sides" is false.
• Option D: A parallelogram is a quadrilateral, and all quadrilaterals have 4 angles. So, the statement "A parallelogram has exactly 2 angles" is false.

Answer:

A. A trapezoid has one pair of parallel sides.
