What’s on the Transformations poster
A 6-row table: Transformation · Plain word · Rule.
A transformation maps every point of a shape to a new position.
- Translation — slide — (x, y) → (x+a, y+b)
- Reflection over x-axis — flip — (x, y) → (x, −y)
- Reflection over y-axis — flip — (x, y) → (−x, y)
- Rotation 90° about origin — turn — (x, y) → (−y, x)
- Rotation 180° — turn — (x, y) → (−x, −y)
- Dilation — resize — (x, y) → (kx, ky)
Translations, reflections and rotations preserve congruence. Dilations produce similar figures instead.
Questions about the Transformations poster
- What’s on the Transformations poster?
- A 6-row table: Transformation · Plain word · Rule. A transformation maps every point of a shape to a new position. Translation — slide — (x, y) → (x+a, y+b); Reflection over x-axis — flip — (x, y) → (x, −y); Reflection over y-axis — flip — (x, y) → (−x, y); Rotation 90° about origin — turn — (x, y) → (−y, x); Rotation 180° — turn — (x, y) → (−x, −y); Dilation — resize — (x, y) → (kx, ky). Translations, reflections and rotations preserve congruence. Dilations produce similar figures instead.
- Who is the Transformations poster for?
- Transformations is filed under 8th Grade (ages 13–14), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Transformations poster?
- Only dilation changes the size. The other three keep the shape identical. A wall chart earns its place by being glanceable from where the work is happening, so Transformations belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Transformations?
- Angles and Parallel Lines, The Pythagorean Theorem and Volume of Cones, Cylinders and Spheres sit alongside Transformations in the 8th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Angles and Parallel LinesThe Pythagorean TheoremVolume of Cones, Cylinders and Spheres
- Is the Transformations poster free to download and print?
- Yes. Transformations downloads as a free PDF with no account, no email and no watermark, like everything else in the 8th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Transformations poster print at?
- Transformations is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Transformations loses nothing.Printing guide
