In Euclidean geometry, the base angles cannot be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle. Since a triangle is obtuse or right if and only if one of its angles is obtuse or right, respectively, an isosceles triangle is obtuse, right or acute if and only if its vertex angle is respectively obtuse, right or acute.

Part 1 was scheduled to be released on May 4, 2018, with Part 2 scheduled for May 3, 2019. In April 2015, Marvel announced that Anthony and Joe Russo would direct both parts of Avengers: Infinity War, with back-to-back filming expected to begin in 2016. The same month, Kevin Feige said the films would be two, distinct films ``because they (have) such shared elements, it felt appropriate... to (subtitle the films) like that. But I wouldn't call it one story that's cut in half. I would say it's going to be two distinct movies.'' By May 2015, Christopher Markus & Stephen McFeely signed on to write the screenplays for both parts of the film, which draws inspiration from Jim Starlin's 1991 ``The Infinity Gauntlet'' comic and Jonathan Hickman's 2013 ``Infinity'' comic. Anthony Russo added the film was inspired by 1990s heist films, with Thanos on ``on a smash-and-grab (to acquire the Infinity Stones), and everybody's trying to catch up the whole movie.'' In May 2016, the Russos revealed that they would be retitling the two films, to further remove the misconception that the films were one large film split in two, with Joe stating, ``The intention is we will change (the titles), we just haven't come up with (them) yet.'' That July, Marvel revealed the film's title would be shortened to simply Avengers: Infinity War.
