In What Ways Can We Visualize Linear Transformations Geometrically?

Linear transformations are a way to change shapes and lines in math. Here are a few simple ways to understand them:

Changing Vectors: A linear transformation takes vectors (which are like arrows with direction) in a space called $\mathbb{R}^n$ and turns them into new arrows. This keeps the basic rules of adding arrows together and multiplying them by numbers.
Shaping Geometry: You can see linear transformations by watching how simple shapes, like triangles or squares, change. They might stretch out, spin around, or flip over.
Using Matrices: We can use a special tool called a matrix, represented by the letter $A$ , to show these transformations. If we have a vector $x$ , the change it undergoes can be written as $Ax = y$ , where $y$ is the new vector.

When we understand these ideas, we can see more clearly how linear transformations affect shapes and spaces.
