Edward Welbourne 0b822c2209 Examples: use std::atan2 for simper angle calculations ... Using std::atan2 gets the right answer directly from dy and dx, without having to fix up quadrant as we needed to with acos (albeit we have to negate dy in some cases, to match prior sense of angles). In the process, it avoids explicit division, which would be an error when the line's length is zero.
