The video tutorial from MooMooMath introduces trapezoids, a type of quadrilateral with one pair of parallel sides. It explains the properties of trapezoids, including the sum of angles in quadrilaterals. The video also covers isosceles trapezoids, which have two congruent sides and congruent base angles. It demonstrates how to calculate angles in trapezoids, emphasizing the concept of supplementary angles.

What is a trapezoid?

• A quadrilateral with one pair of parallel sides

• A polygon with five sides

• A triangle with two equal sides

• A circle with a diameter
