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.

  6. If two lines are perpendicular to the same line, then they are parallel
  7. When two parallel lines are cut by a transversal resulting in corresponding angles making them congruent
  8. Any ray, segment, or line that intersects a segment at its midpoint. It divides a segment into two equal parts at its midpoint
  9. Division of something into two equal or congruent parts by a bisector
