  ## Pythagorean Theorem 2
  
  Directions: Using the digits 0 to 9, at most one time each, fill in the boxes to find the lengths of the missing sides such that the missing leg’s length is as long as possible. Source: Robert Kaplinsky
  
  ## Pythagorean Theorem
  
  Directions: Using the digits 0 to 9, at most one time each, fill in the boxes to find two pairs of possible lengths for the missing sides. Source: Robert Kaplinsky
  
  ## Partitioning a Line Segment
  
  Directions: Using the digits 1 to 8 exactly one time each, fill in the boxes to create a line segment AB, where between point A and point B, there exists a point P so that it partitions line segment AB into a ratio. Source: Jon Henderson
