Across
  1. 3. Two lines that intersect to form a 90° angle
  2. 6. A transformation across a line, called the line of reflection
  3. 8. Is formed by two or more different regular polygons, with the same number of each polygon occurring in the same order at every vertex
  4. 14. A change in position, size or shape of a figure
  5. 15. Divides the figure into two congruent halves
  6. 18. A transformation that turns a figure around a fixed point, called the center of rotation
  7. 19. A transformation that changes the size of a figure but not the shape or direction

Down
  1. 1. A transformation where all the points of a figure are moved the same distance in the same direction
  2. 2. When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles
  3. 4. Two lines in the same plane that, no matter how far they extend, do not intersect with each other

  5. 7. Two Angles that add up to 90 degrees
  6. 8. Interior angles may be defined as two interior angles lying on the same side of the transversal cutting across two parallel lines
  7. 9. A transformation that does not change the shape or size of a figure
  8. 10. Is formed by congruent regular polygons
  9. 11. Angles that are formed on opposite sides of the transversal but outside the two lines
  10. 12. Two angles that add up to 180 degrees
  11. 13. Angles that are formed on opposite sides of the transversal and inside the two lines
