Write a rule to describe a transformation when a triangle hasbeen reflected over the x-axis.(x,y) →Using (-x,-y)

Sagot :

For a transformation that involves a reflection over the x-axis, it means the pre-image is reflected across the horizontal line.

For a reflection over the x-axis, the x coordinate remains the same while the y coordinate changes.

The rule that describes a transformation when an image has been reflected over the x-axis is:

(x, y) ==> (x, -y)

Using the pre-image (-x, -y), we have:

(-x, -y) ==> (-x, y)

For a triangle, we have:

A(-x, -y) ==> A'(-x, y)

B(-x, -y) ==> B'(-x, y)

C(-x, -y) ==> C'(-x, y)
