Question

does this shape belong in a group of shapes that have more than one pair of perpendicular sides? use the drop-down menus to explain your answer. click the arrows to choose an answer from each menu. the number of right angles in this shape is choose... . each pair of sides that meet at a right angle is choose... . each pair of perpendicular sides in this shape. this shape... in a group of shapes that have more than one pair of per... sides.

Explanation:

Step1: Count right angles

The shape (a quadrilateral) has two right - angled marks, so the number of right angles is 2.

Step2: Relate right angles to perpendicular sides

Each right angle is formed by a pair of perpendicular sides. So if there are 2 right angles, there are 2 pairs of perpendicular sides.

Step3: Determine group membership

Since the shape has 2 pairs of perpendicular sides (more than one pair), it belongs in the group of shapes with more than one pair of perpendicular sides.

Answer:

The number of right angles in this shape is 2. Each pair of sides that meet at a right angle is a pair of perpendicular sides in this shape. This shape belongs in a group of shapes that have more than one pair of perpendicular sides.
