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. Division of something into two equal or congruent parts by a bisector
  2. Any ray, segment, or line that intersects a segment at its midpoint. It divides a segment into two equal parts at its midpoint
  3. Coordinate Plane
  4. If the corresponding angles formed by two lines and a transversal are congruent, then the lines are parallel.
  5. If x = y, and y = z, then x = z.
  6. Slopes of Perpendicular Lines Theorem
  7. Parallel Postulate
  8. When two parallel lines are cut by a transversal resulting in corresponding angles making them congruent
  9. If two lines are cut by a transversal and the consecutive exterior angles are supplementary then the two lines are parallel
  10. If 2 planes intersect, it creates a line.
  11. Two or more lines that go in the same directions staying the same distance apart. In addition they never intersect!
