Mathematics - Geometry - Transformations - Reflections - Reflection Explorer
A coordinate grid with a shape and a reflection line (adjustable: x-axis, y-axis, y=x, or custom). The student sees the reflection appear on the other side of the line. Key rules: reflecting over x-axis → (x,y) becomes (x,-y). Over y-axis → (-x,y). Over y=x → (y,x). The student moves the shape and s
