This example demonstrates the construction of an isosceles trapezoid. An isosceles trapezoid is a special type of trapezoid with two equal non-parallel sides. Key construction commands used include Line, Mirror, Polygon, and Segment. By adjusting the base and side lengths, the properties of the isosceles trapezoid can be observed. Suitable for middle and high school students learning geometric construction.
