Translation
8.G.A.1
Definition
A transformation that slides every point of a figure the same distance in the same direction. The image is congruent to the original.
Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
Examples
- (x, y) → (x+5, y+3) slides right 5 and up 3.
- Size, shape, and orientation stay the same.
Key rule
A translation is a rigid motion — the image stays congruent.
Memory hook
A slide — everything moves the same way.
