The video tutorial covers the properties and formulas of quadrilaterals, including squares, rectangles, rhombuses, and parallelograms. It demonstrates problem-solving using these formulas, with a focus on applying Pythagorean triples in quadrilateral problems. The tutorial also explores breaking down complex quadrilaterals into triangles to find areas, emphasizing the importance of understanding geometric properties and relationships.
