This geometry video tutorial provides a basic introduction into isosceles trapezoids. It discusses the basic properties of isosceles trapezoids. The bases are parallel and the legs are congruent. The lower base angles are congruent and the upper base angles are congruent. The lower base angles and the upper base angles form consecutive interior angles also known as same side interior angles and are therefore supplementary. This video contains plenty of examples and practice problems on isosceles trapezoids. It discusses how to calculate the area of an isosceles trapezoid as well as calculating missing sides and angles. Finally, this video discusses the midsegment theorem of a trapezoid.
