Write a slide with arrows
How do you write a slide in the fewest marks?
Today you'll discover
- what each arrow means
- which number comes first
- how to slide a point from arrows
Think firstA triangle and a slide written 5 →, 2 ↑
What does 5 →, 2 ↑ tell the triangle to do?
Decide first, then press Next. Read each number with its own arrow.
A coordinate grid with a triangle, corners A (1, 4), B (3, 7) and C (6, 5). The list beside the grid writes the slide as 5 right-arrow, 2 up-arrow; L-shaped arrows take each corner 5 right and 2 up, to (6, 6), (8, 9) and (11, 7), and the new corners join into a green triangle facing the same way.

The big idea
A translation vector writes a slide as arrows, across first: 5 →, 2 ↑.
Four arrows
Each arrow is a direction; its number says how far.
- →right
- ←left
- ↑up
- ↓down
Key word
- translation vector
- a slide written as a distance and direction across, then up or down: 5 →, 2 ↑
