The video tutorial covers the concept of symmetry, focusing on line symmetry. It begins with an introduction to symmetry and the learning objectives. The teacher explains line symmetry using examples, demonstrating how a shape can be folded along a line to create two matching halves. The video includes examples of shapes with and without line symmetry and guides students through analyzing figures to determine symmetry. Finally, it provides instructions on drawing symmetrical shapes using guides, emphasizing the importance of equal distances and lengths.
