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. (x1+x2/2, y1+y2/2)
  2. Division of something into two equal or congruent parts by a bisector
  3. If a=b, then ac=bc
  4. y=mx+b
  5. Slopes of Perpendicular Lines Theorem
  6. Two or more lines that go in the same directions staying the same distance apart. In addition, they never intersect!
  7. If two lines are perpendicular to the same line, then they are parallel
  8. If two lines are cut by a transversal and the consecutive exterior angles are supplementary, then the two lines are parallel
  9. If x = y, and y = z, then x = z
  10. Substitution Prop/POE
  11. Alternate Exterior Angles Converse
  12. Part of a line that has 2 endpoints
  13. If a=b, then ac=bc
  14. Plane
  15. √(x2−x1)^2+(y2−y1)^2
  16. Any ray, segment, or line that intersects a segment at its midpoint. It divides a segment into two equal parts at its midpoint
  17. If a = b, b = a; you can flip the sides of an equation.
  18. If the corresponding angles formed by two lines and a transversal are congruent, then the lines are parallel.
  19. A part of a line that starts from one point and extends in one direction for an infinite amount of time
  20. When two parallel lines are cut by a transversal resulting in corresponding angles making them congruent
  21. Identity Property of Division
  22. Coordinate Plane
  23. A mark that models/indicates an exact position and location in a space
  24. Parallel Postulate
