Another Angle: Hints

• The left clues are regular clues. The right clues are the wordplay parts of cryptic clues.
• The answer to each clue is a word (or in one case, a two-word term).
• The answers to the clues should be put in the grid.
• There's only one intended way to put the answers to the clues in the grid.
• Each type of clue (regular and wordplay) is given in order of the answer lengths, and the answer lengths within each type are 1 to 12 once each.
• Put an answer to a regular clue to the left of the black space in each row (unless the black space is on the furthest-left cell), and an answer to a wordplay clue to the right (unless the black space is on the furthest-right cell).
• This hint clues an aha moment. Why is the puzzle titled "Another Angle"?
• This hint clues an aha moment. What could you put at another angle? And how could you get one letter from each row of the given grid?
• This hint strongly clues an aha moment. No, you don't put the filled grid at another angle.
• This hint gives away an aha moment. Overlay the unfilled grid at another angle on the puzzle, and look at the letters on the black spaces.
• What angle do you want to rotate the unfilled grid by to get a clue?
• Each of 90 degrees clockwise, 90 degrees counterclockwise, and 180 degrees gives a different clue.
• No word answers all three clues (as far as I know).
• Is there any way to choose the answers to the clues so that they have something in common?
• The flavortext says "the answer to the puzzle is missing".
• The answers to the clues are three of four items in a common set.
• What's the fourth item in that set (the missing one)?
