Angle Loop

Draw straight lines from clue to clue to form a single loop that doesn’t cross or touch itself, and that passes every clue. The loop must turn at every clue, with an angle that is acute (< 90°) for triangles, right (=90°) for squares, and obtuse (>90°, <180°) at pentagons.

I first saw this type in the Toketa books.

        Is this better? Replaced “Connect clue polygons by straight lines t form …” by “Draw straight lines from clue to clue to form …”. I’m meaning to express that the loop is built from straight segments that have clues at both ends.

    The rules are not adequately stated yet. This puzzle is solvable if ‘either’ of the two angles made at each node satisfies the conditions. If the inner angle is considered, the puzzle has no solution.
