Translations — Notes & Worked Examples Show / Hide

Explanation:

A translation slides a shape without rotating, reflecting, or resizing it. Translations are written using a column vector x
y
, where the top number x is the horizontal movement (+ right, − left) and the bottom number y is the vertical movement (+ up, − down).

When finding the translation vector from shape A to shape B, always pick one matching corner on both shapes (e.g. the top-right corner to the top-right corner) rather than counting the gap between the two shapes.

Example 1: Point A(2, −1) is translated by −5
4
. Find A'.

A(2,−1) A'(−3,3) −5 +4
Move 5 left, 4 up:
x = 2 − 5 = −3
y = −1 + 4 = 3 → (−3, 3)

Example 2: Top-left vertex of P is (−3, 5) and top-left of Q is (2, 1). Describe the transformation from P to Q.

P Q +5 −4
−3 to 2: +5 (right)
5 to 1: −4 (down)
Translation 5
−4
