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. Part of a line that has 2 endpoints
  3. If the corresponding angles formed by two lines and a transversal are congruent, then the lines are parallel.
  4. If a = b, b = a; you can flip the sides of an equation.
  5. A mark that models/indicates an exact position and location in a space
  6. y=mx+b
  7. A part of a line that starts from one point and extends in one direction for an infinite amount of time
