Geometric transformation is when we change the shape or position of something, like a picture or a toy. Imagine you have a puzzle with different shapes and you want to move them around or flip them over to make a different picture. That's geometric transformation!
Okay, so let's say you have a square. If you slide it to the left or right or up or down, you can change its position. If you stretch it out on the sides or make it taller, you can change its shape. You may also rotate it, which means you turn it around to look at it from a different angle.
Another example is if you have a toy car and you want it to look like it's going up a ramp. You can tilt the car and make it higher so it looks like it's going up. This is a kind of geometric transformation too.
So, geometric transformation is when we change the shape, size or position of something, like moving a toy or changing the shape of a puzzle piece.
