Question

On a coordinate plane, 2 triangles are shown. The first triangle has points A (negative 2, 1), C (negative 4, 1), and B (negative 3, 4). The second triangle has points A prime (1, negative 2), B prime (4, negative 3), and C prime (1, negative 4). What is the rule for the reflection?

Answer 1

Answer:

The answer is "$\bold{R(y=x) = (x, y) \to (y, x)}$"

Explanation:

If A coordinates are = (-2, 1)

so,

The coordinates of A' = (1, -2)

Its values had also obviously been replaced order are:

$= (x, y) \to (y, x)$

Now that's the product of an overview of y = x. That's why the rule and its name is: $R(y=x) = (x, y) \to (y, x)$.
