Question

5
select the correct shapes.
select all of the shapes that have at least one pair of parallel sides.

Explanation:

Step1: Analyze the triangle

A triangle (the purple shape) has three sides, and by the definition of a triangle, its sides meet at angles, and there are no parallel sides. So it is excluded.

Step2: Analyze the rectangle

A rectangle (the orange shape) has opposite sides that are parallel. By the properties of a rectangle, both pairs of opposite sides are parallel, so it has at least one pair (in fact two pairs) of parallel sides.

Step3: Analyze the pink quadrilateral

The pink quadrilateral appears to be a trapezoid? No, looking at its sides, none of the sides seem to be parallel (visually, the sides are not aligned in a way that they would never meet if extended). So it is excluded.

Step4: Analyze the parallelogram

A parallelogram (the green shape) has both pairs of opposite sides parallel by definition. So it has at least one pair (two pairs) of parallel sides.

Answer:

The orange rectangle and the green parallelogram (the second shape in the top row and the fourth shape in the bottom row) are the shapes with at least one pair of parallel sides.
