Affine transformation, an Uncommon card
In Euclidean geometry, an affine transformation or affinity is a geometric transformation that preserves lines and parallelism, but not necessarily Euclidean distances and angles.

Affine transformation quiz: 3 questions
Three questions on the Affine transformation card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Consequently, sets of ______ affine subspaces remain parallel after an affine transformation.
Answer
parallel. Consequently, sets of parallel affine subspaces remain parallel after an affine transformation. From the Affine transformation article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Harmonica. Harmonica 75 · Dielectric 72 · Affine transformation 69 · Friesian horse 66 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Male. Male 290,000 · Hexagon 190,000 · Affine transformation 140,000 · Poison 110,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- More generally, an affine transformation is an automorphism of an affine space, that is, a function which maps an affine space onto itself while preserving both the dimension of any affine subspaces and the ratios of the lengths of parallel line segments.
- Consequently, sets of parallel affine subspaces remain parallel after an affine transformation.
- An affine transformation does not necessarily preserve angles between lines or distances between points, though it does preserve ratios of distances between points lying on a straight line.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Affine transformation article was read about 140,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 59: each hit it takes is cut by 24 %.
How to get Affine transformation
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
