# Max Maths, Year 2, Learn together, Symmetry of figures (4)

In a Year 2 mathematics lesson from Max Maths, students explore the concept of symmetry through hands-on activities. Padma begins the exploration by drawing an equilateral triangle, which is a triangle with all three sides of equal length. She discovers that this shape has a line of symmetry—a line that divides the shape into two identical parts—running from the top vertex straight down to the midpoint of the base. This line of symmetry is one of the unique features of an equilateral triangle, demonstrating how the shape can be folded along this line to match perfectly on both sides.

Jade and Samir further investigate the equilateral triangle and each find additional lines of symmetry. When Jade turns the paper around, she identifies a second line of symmetry, and Samir discovers a third one after turning the paper yet again. Through this activity, students learn that an equilateral triangle has three lines of symmetry in total, each line running from a vertex to the midpoint of the opposite side. This lesson on the symmetry of figures is designed to be interactive and engaging, encouraging students to physically manipulate shapes to find lines of symmetry. For more exercises and detailed explanations, students are directed to work through pages 72 to 75 in their workbooks.
