Question

(16.05 MC)

What two attributes have been used to sort these shapes?

Two groups of shapes, group A and B. Group A has three shapes. The first shape is a quadrilateral with two right angles and one pair of parallel lines, the second shape is a square, and the third shape is a rectangle. Group B has three shapes. The first shape is a quadrilateral that has two pairs of sides equal in length and no right angles, the second shape is a parallelogram with no right angles, and the third shape is a quadrilateral with two pairs of sides equal in length but no right angles and no parallel lines.

Shapes with perpendicular sides and shapes without perpendicular sides
Shapes with parallel sides and shapes without parallel sides
Shapes with equal sides and shapes with unequal sides
Shapes with equal angles and shapes with unequal angles
what is correct

Answer 1

(a) Shapes with perpendicular sides and shapes without perpendicular sides

Explanation:

This appears to be a reading comprehension problem, along with a requirement that you recognize squares and rectangles have right angles and pairs of parallel equal-length sides.

The group descriptions are very careful to say that the members of Group B have no right angles. Members of both groups have equal-length sides and parallel lines, so those are not distinguishing criteria.

The relevant attribute for sorting appears to be right angles/no right angles.
