Question

which group of shapes is sorted correctly?
group a
two pairs of parallel sides
shapes
group b
at least one square corner
shapes
neither group a nor group b
group b only
both group a and group b
group a only

Explanation:

Step1: Analyze Group A's criteria

Group A is defined as shapes with two pairs of parallel sides.

• The first shape (a kite-like quadrilateral) has no parallel sides, violating the rule. So Group A is sorted incorrectly.

Step2: Analyze Group B's criteria

Group B is defined as shapes with at least one square (90°) corner.

• Rectangle: 4 square corners ✔️
• Irregular quadrilateral: 1 square corner ✔️
• Right trapezoid: 2 square corners ✔️
• Rhombus (square-like): 4 square corners ✔️

All shapes meet the rule, so Group B is sorted correctly.

Step3: Final determination

Only Group B is sorted correctly.

Answer:

Group B only
