Question

choose all answers that describe the quadrilateral cdef if cd || ef and de || fc. answer attempt 1 out of 2 parallelogram rectangle rhombus square trapezoid

Explanation:

Step1: Recall quadrilateral definitions

A parallelogram has two pairs of parallel - sides. Since \(CD\parallel EF\) and \(DE\parallel FC\), \(CDEF\) is a parallelogram.

Step2: Analyze other quadrilateral requirements

A rectangle has four right - angles, a rhombus has four equal - length sides, a square has four right - angles and four equal - length sides. There is no information about angles or side lengths, so we cannot say it is a rectangle, rhombus, or square.

Step3: Recall trapezoid definition

A trapezoid has exactly one pair of parallel sides. Since \(CDEF\) has two pairs of parallel sides, it is not a trapezoid.

Answer:

Parallelogram
