The video tutorial teaches how to classify quadrilaterals based on their sides, focusing on identifying parallel lines. It explains the properties of parallel lines and how they determine the classification of shapes into kites, trapezoids, or parallelograms. The tutorial includes examples and practice problems to reinforce learning, guiding viewers through the process of identifying and naming quadrilaterals based on the number of parallel sides and equal side lengths.
