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. Parallel Postulate
  2. (x1+x2/2, y1+y2/2)
  3. If two lines are perpendicular to the same line, then they are parallel
  4. Slopes of Perpendicular Lines Theorem
  5. If a=b, then ac=bc
  6. When two parallel lines are cut by a transversal resulting in corresponding angles making them congruent
  7. If x = y, and y = z, then x = z
  8. Identity Property of Division
  9. A part of a line that starts from one point and extends in one direction for an infinite amount of time
  10. A mark that models/indicates an exact position and location in a space
  11. Any ray, segment, or line that intersects a segment at its midpoint. It divides a segment into two equal parts at its midpoint
