Triangle ABC has vertices A(−2, 0), B(2, 5), C(3, 1). The reflection of the image of triangle ABC is triangle A'B' C' with vertices A'(−2, 0), B'(2, −5), C'(3, −1). What is a rule that describes the reflection?

Relax

Respuesta :

Looks like the triangle ABC has been reflected over the x axis. One rule to describe this reflection is:

When a coordinate point is reflected over the x axis, the x coordinate stays the same while the y coordinate changes.

Example:

(2,1) to (2,-1)
