When we talk about changes in shapes in geometry, like rotations and reflections, there are some important differences to know:
Rotations: This is like spinning a shape around a point, which we call the center of rotation. For example, if you take a triangle and spin it 90 degrees to the right, it will look different, but the size and shape will stay the same.
Reflections: This means flipping a shape over a line, which we call the line of reflection. You can think of it like looking at yourself in a mirror. The shape stays the same, but it looks like it flipped around.
So, in short, rotations change how the shape is angled, while reflections create a mirror image of it.
