Where the pins stand in a triangle formation called in bowling?

......1...... ....2...3.... ..4...5...6.. 7...8...9...10 The "Headpin" is #1 (the ball closest to the bowler) The "Middle Pin" or "King Pin" is #5 (the center of the pack) The other pins don't have specific names by themselves, but may in combination (for example, if you knocked down all except the #7 and #10 pins, the two remaining pins would be "Bedposts").
