Understanding Reflections over the Line y=x | Exploring Diagonal Symmetry in Mathematics and Design

reflection over y=x

When reflecting a point, line, or shape over the line y=x, each point’s x-coordinate is swapped with its y-coordinate

When reflecting a point, line, or shape over the line y=x, each point’s x-coordinate is swapped with its y-coordinate. In other words, if a point has coordinates (x, y), its reflection over y=x will have coordinates (y, x).

For example, let’s reflect the point (2, 4) over y=x. Since the x-coordinate of this point is 2 and the y-coordinate is 4, the reflected point will have coordinates (4, 2). This means that the new point is 2 units right and 2 units up from the line of reflection.

Similarly, if we have a line or shape, we can reflect each of its points over y=x to find the corresponding reflected line or shape.

Reflection over y=x is a type of symmetry called diagonal symmetry. It means that if you fold the figure along the line y=x, the two halves would perfectly match each other.

This concept is very useful in various areas of mathematics and geometry, as well as in art and design. It allows us to create balanced and visually appealing compositions.
