Across
  1. 3. angles smaller than 90 degrees
  2. 6. angles with a sum of 90 degrees
  3. 7. the line that cuts two parallel lines
  4. 9. Angles in the same place on different lines, they are equal. Make an "F" shape
  5. 10. angles between 90 and 180 degrees
Down
  1. 1. angles which form a "Z" shape, on opposite sides of the transversal, which are equal
  2. 2. angles that are across from one another and equal to one another. Form an "X" shape.
  3. 4. angles with a sum of 180 degrees
  4. 5. angles on the same side of a transerval, sum to 180 degrees
  5. 8. a perfect 90 degree angle
