How do you represent a translation mathematically?

Back

A translation can be represented as (x + a, y + b), where (a, b) are the horizontal and vertical shifts, respectively.

What is the effect of translating a triangle on its size and shape?

Back

Translating a triangle does not change its size or shape; it only changes its position.
