Isosceles Trapezoid Construction by Wendy Sanchez
Loading the math board and drawing, please wait…
This example demonstrates the construction of an isosceles trapezoid. An isosceles trapezoid is a special type of trapezoid with two equal non-parallel sides. Using GeoGebra commands such as Segment (line segment), Line (line), Intersect (intersection), Angle (angle), etc., an isosceles trapezoid can be constructed. This example is suitable for middle and high school students to learn geometric construction and understand the properties and construction methods of isosceles trapezoids.
