Trapezoid - Definitions and constructions

***************************************************************************** Our minimal definition: Trapezoid - a quadrilateral with at least one pair of parallel sides. ***************************************************************************** Construct a trapezoid. Then observe other constructions and answer the questions below.

Your construction:

What is the definition on which your construction is based?

Other trapezoid constructions

If you want to follow the construction steps, use the navigation buttons at the bottom to scroll through the steps. If you want to see the description/definition of an object, right click it (control+click on Mac).

Construction 1:

C1: What definition is this construction based on?

Construction 2:

C2: What definition is this construction based on?

Construction 3:

This is a "reverse" question. Given the definition below, decide if it is a valid definition of a trapezoid, equivalent to our minimal definition. You may want to construct it strictly from the definition and then play with your construction to formulate your conclusion. *********************************************************************************************** A quadrilateral, in which a line perpendicular to two sides exists. ***********************************************************************************************
