I WONDER - What Is An Isosceles Trapezoid?

The video explains the properties of an isosceles trapezoid, highlighting that if the nonparallel sides are equal, it is called an isosceles trapezoid. The angles at the base are equal, and it has a line of symmetry. Additionally, both diagonals are equal in length.
