Transformations in Year 7 geometry are super interesting! Let’s break down the main ideas:
Translation: This means moving a shape to a new spot without turning it or flipping it. Imagine sliding it across a flat surface. The shape stays the same size and looks the same. For example, if you move a point A(2,3) to the right and up, it can turn into A'(4,5).
Rotation: This is like spinning a shape around a point. The angle you spin it matters. For instance, if you rotate a triangle 90 degrees around one of its corners, it will change its direction but stay the same size.
Reflection: Think of flipping a shape over a line, like looking in a mirror. The original shape and its reflection are exactly the same.
Enlargement: This means making a shape bigger while keeping its shape the same. If you enlarge a rectangle by a factor of 2, it will double in size!
Understanding these ideas helps you see how shapes move and change in space!
