Translations
Explanation
A translation slides a shape up, down, left, right, or diagonally.
Key points:
-
Each point moves the same distance in the same direction
-
Shape and orientation do not change
Notation: T(x, y) → (x + a, y + b)
-
a = horizontal movement
-
b = vertical movement
Example: Translate (2,3) by (4, −1) → (2+4, 3−1) = (6, 2)
