🪞 Reflections & Lines of Symmetry
Explore reflections and lines of symmetry in 2D shapes. Learn to identify lines of symmetry, reflect shapes across vertical, horizontal, and diagonal lines, and understand how reflections create mirror images on a grid. **What you'll learn:** - Identify lines of symmetry in common 2D shapes - Perform reflections across vertical, horizontal, and diagonal lines - Recognize symmetric and asymmetric figures - Plot reflected points on a coordinate grid
