Line–line intersection quiz: 3 questions
Three questions on the Line–line intersection card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
In a ______ space, if two lines are not coplanar, they have no point of intersection and are called skew lines.
Answer
Euclidean. In a Euclidean space, if two lines are not coplanar, they have no point of intersection and are called skew lines. From the Line–line intersection article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Coach. Coach 48,000 · Line–line intersection 38,000 · Acrobatic gymnastics 19,000 · Boiler 14,000 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.
- Distinguishing these cases and finding the intersection have uses, for example, in computer graphics, motion planning, and collision detection.
- In a Euclidean space, if two lines are not coplanar, they have no point of intersection and are called skew lines.
- If they are coplanar, however, there are three possibilities: if they coincide, they have all of their infinitely many points in common, if they are distinct but have the same direction, they are said to be parallel and have no points in common, otherwise, they have a single point of intersection, denoted as singleton set, for instance { A }.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Line–line intersection article was read about 38,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 50: each hit it takes is cut by 20 %.
How to get Line–line intersection
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.
