Question

to build the roof for a paper house, a rectangular paper is cut to form a trapezoid. which diagram shows the correct cuts?

Explanation:

Step1: Recall the definition of a trapezoid

A trapezoid has one pair of parallel sides.

Step2: Analyze each diagram

• In the first diagram, after cutting, the resulting figure has one pair of parallel sides (the original parallel sides of the rectangle are still there for the trapezoid part).
• In the second diagram, the cut creates a triangle - like top part instead of a trapezoid.
• In the third diagram, the cut does not result in a trapezoid.
• In the fourth diagram, the cut does not result in a trapezoid.

Answer:

The first diagram.
