Using the definition of a trapezoid, the segment within a large playlist on basic geometry explains other properties of trapezoids. The video introduces the special properties held by isosceles trapezoids.

Transform trapezoids to a T. Pupils identify reflections and rotations that take trapezoids and map them back to themselves. They consider both isosceles and non-isosceles trapezoids.

Prove the diagonals are shorter than the perimeter. Given an isosceles trapezoid, pupils develop a proof relating the length of the diagonals to the perimeter. Individuals sketch a graph of the trapezoid to assist with their explanations.
