Reflective symmetry is when you have a shape (a letter for example, even though they are weird shapes) and you can put a line through it called a mirror line. On the mirror line you put a mirror on it and you can see a half of the shape reflected to make the complete shape.You must be able to do this on both sides of the shape otherwise it won't have reflective symmetry.Take the letter E for example. If you put a line straight through the middle of it horizontally it would be a mirror line.
Visualising solid shapes is a very useful skill. We can see the hidden parts of a solid shape. For example, when a cuboid with a square face is cut vertically, then each face is a square. The face is a cross section of the cuboid
