Determine the answer to each definition or postulate below.
Then write the word in the 11 by 11 matrix using the following rules:
- Each word makes one right-angle turn somewhere along its length. But you must determine where each word makes this turn and in which direction.
- As a guide, the starting direction (i.e., the direction of the word before its right angle turn) of each answer is indicated by the letter given after the clue number.
- Words can go North, South, East, or West to start with. For example, 1S begins on square 1 and heads South.
- Each letter in the correctly completed grid appears in only one word.
