Follow one thing on paper: what you see, where it goes after a turn or a flip, where a face lands when folded. Don't turn the whole shape in your head.

  1. 1

    Don't turn the shape, turn one arrow

    When to use it: A shape is turned a quarter turn, a half turn or some angle, and the question asks which picture it becomes, where a point ends up, or how many degrees it turned; on a grid it may turn about a point or be slid afterwards.

    • Don't turn the whole shape. Pick one arrow to turn: a drawn arrow, a long arm or a point. If there isn't one, draw one.
    • Clockwise goes up, right, down, left; a quarter turn goes to the next word.
    • If two options are still alive, turn a second arrow.
    • A slide doesn't change the arrow: turn that one step and skip the slide.
    • Clockwise plus anti-clockwise makes 360°.
