Draw the translated parallelogram.
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'.
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.

Worked Solution & Answer
(5 − 6, 1 + 2) = (−1, 3)
(5 − 6, 3 + 2) = (−1, 5). A1
