Geometry Bingo - Call List

(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

  1. Plane
  2. Lines that intersect at a right angle
  3. Parallel Postulate
  4. Alternate Exterior Angles Converse
  5. If the corresponding angles formed by two lines and a transversal are congruent, then the lines are parallel.
  6. If x = y, and y = z, then x = z.
  7. A mark that models/indicates an exact position and location in a space
  8. (x1+x2/2, y1+y2/2)
  9. Division of something into two equal or congruent parts by a bisector
  10. If two lines are perpendicular to the same line, then they are parallel
  11. Identity Property of Division
  12. When two parallel lines are cut by a transversal resulting in corresponding angles making them congruent
  13. If a=b, then ac=bc
