In this lesson I will teach you about trapezoids.  A trapezoid is a special type of quadrilateral.  Just like a parallelogram is a special quadrilateral so is the trapezoid and this lesson will focus entirely on what makes a trapezoid unique.  As you will see in the video the trapezoid is more involved than a parallelogram.   Hence you want to take your time with the lesson so you understand the parts and terms related to a trapezoid.  It’s easy for a student to get quadrilateral theorems and properties confused so make sure your notes are well organized and clear.  Quick pop quiz: do you know the difference between a parallelogram and a trapezoid?  Well if you said a trapezoid only has one pair of parallel sides where a parallelogram has both pairs of opposite sides parallel you would be correct.  Also, the area formulas for a parallelogram and trapezoid are much different as well.  Like I was saying trapezoids have more aspects we need to study than parallelograms and each detail is important.  Don’t forget to keep reviewing algebra- you will see algebra used in many geometry problems so keep your skills sharp.
