To understand reflections in geometry, here are a few easy ways to visualize them:
Grid Paper: When you draw shapes on grid paper, it helps you see how they flip over a line.
Tracing Paper: You can use tracing paper to turn shapes over the line of reflection and see where they land.
Geometric Software: There are computer programs like GeoGebra that let you change shapes and see their reflections right away.
Let’s look at an example!
If you have a triangle and you flip it over the line (y = x), the points of the triangle will change.
Imagine your original triangle has points at (1, 2), (2, 3), and (3, 1).
After reflecting it, the new points will be at (2, 1), (3, 2), and (1, 3).
You can really see how the picture changes!
