(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.

A triangle with 1 right angle and 2 acute.
Right
When 2 angles sum to 90°.
Complementary
When 2 angles sum to 180°.
Supplementary
Non-adjacent angles formed by intersecting lines.
Vertical Angles
A triangle with 2 congruent sides and angles.
Isosceles
If tick-tick, then...
Swoosh-Swoosh
The interior angles of a triangle add up to this.
180°
2 adjacent, supplementary angles.
Linear Pair
Lines that intersect at a right angle.
Perpendicular
A triangle with 3 congruent sides.
Equilateral
When 2 or more angles have the same measure, they are what?
Congruent
A shape with 3 sides and angles.
Triangle
If swoosh-swoosh-swoosh, then...
Tick-Tick-Tick
The measure of this angle is found by adding the measures of the 2 non-adj interior angles.
Exterior Angle
If swoosh-swoosh, then...
Tick-Tick
Lines that are not in the same plane, are not parallel, and will never intersect.
Skew
A triangle with no congruent sides or angles.
Scalene
A point that joins 2 sides of a triangle.
Vertex
Also called a "slide".
Translation
Angles on the opposite side of the transversal and outside the 2 lines.
Alternate Exterior Angles
A triangle with 3 acute angles.
Acute
The 2 acute angles of a right triangle add up to this.
90°
When a side is directly across from an angle, we call it this.
Opposite Side
A triangle with 3 congruent angles.
Equiangular
Angles that lie in the same spot or "match-up".
Corresponding Angles
Angles on the same side of the transversal and inside the 2 lines.
Same-Side Interior Angles
A triangle with 1 obtuse angle and 2 acute.
Obtuse
Lines in the same plane that never intersect.
Parallel
