Question

fill in the sentence below with the description that most specifically applies to the quadrilateral below.
answer attempt 1 out of 2
the quadrilateral is most specifically a rectangle, because all angles measure 90° it is equilateral and all angles are congruent all sides are parallel exactly one pair of sides is parallel

Explanation:

Step1: Recall the properties of a rectangle

A rectangle is a quadrilateral with four right angles ($90^{\circ}$).

Step2: Analyze each option

• "all angles measure $90^{\circ}$": This is a key property of a rectangle.
• "it is equilateral and all angles are congruent": A rectangle is not equilateral (sides are not all equal).
• "all sides are parallel": In a rectangle, opposite sides are parallel, not all sides (adjacent sides are perpendicular).
• "exactly one pair of sides is parallel": A rectangle has two pairs of parallel sides.

Answer:

all angles measure $90^{\circ}$
