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