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