(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.

centroid
inscribed
triangle midsegment theorem
inscribed circle.
median
circumcircle
incenter
point of concurrency
the point of concurrency of the perpendicular bisectors of a triangle.
angle bisector theorem
the intersection (or point of concurrency) of the lines that contain the altitudes.
an angle whose vertex is on a circle and whose sides contain chords of the circle.
a line segment that connects the midpoints of two sides of a triangle.
the circle that contains the three vertices of a triangle.
incircle
a circle that contains all the vertices of a polygon on the circumfrence of the circle.
circumcenter
the angle bisectors of a triangle intersect at a point that is equidistant from the sides of the triangle.
midsegment
if a point is on the bisector of an angle, then it is equidistant from the sides of the angle.
center of the circle.
a segment whose endpoints are a vertex of a triangle and the midpoint of the opposite side.
a perpendicular segment from a vertex to the line containing the opposite side.
concurrent
centroid theorem
if a point in the interior of an angle is equidistant from the sides of the angle, then it is on the bisector of the angle.
orthocenter
converse of the angle bisector theorem
the circumcenter of a triangle is equidistant from the vertices of the triangle.
the intersection of three medians of a triangle.
circumcenter theorem
incenter theorem
the centroid of a triangle is located 2/3 of the distance from each vertex to the midpoint of the opposite side.
altitude
the point of intersection of concurrent lines.
three or more lines that intersect at the same point.
circumscribed
Free!
the segments joining the midpoints of two sides of a triangle is parallel to the third side, and its length is half the length of that side.
