In this lesson, we explore Theorem 6.6: The Ratio of Areas of Similar Triangles from the NCERT Class 10 Maths book. The theorem states that the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.📐✨

This important concept is also referred to as the ‘Area Theorem for Similar Triangles’ or ‘Proportional Area Theorem’. In this lesson, I’ll guide you through the step-by-step proof with a clear explanation for each step. 🎓📘
