This video tutorial covers the classification of triangles and quadrilaterals. It begins with an introduction to the topic, followed by detailed explanations on how to classify triangles based on their angles and sides. The tutorial then combines these methods to classify triangles using both criteria. The latter part of the video introduces quadrilaterals, explaining their types and how to classify them, including parallelograms. The session concludes with practical examples to reinforce the learning objectives.
