Question

select all the trapezoids.

Explanation:

Step1: Recall trapezoid definition

A trapezoid is a 4-sided polygon with at least one pair of parallel sides.

Step2: Analyze each shape

1. Top-left: 7-sided heptagon → Not a trapezoid.
2. Top-right: 4-sided shape, 1 pair of parallel sides (marked by arrows, right angles confirm perpendicularity to base) → Trapezoid.
3. Bottom-left: 4-sided shape, 1 pair of parallel sides (marked by arrows, right angles confirm perpendicularity to top side) → Trapezoid.
4. Bottom-right: 5-sided pentagon → Not a trapezoid.

Answer:

Top-right quadrilateral, Bottom-left quadrilateral
