To do this you would use Pathagreon's Theory. 602 + 602 = (square root of) 7200 = ~84.85 feet. This represents that straight line between the bases. It measure from the tip of one bag to the tip of the other bag.
it's 60 feet.
the pitching distance varies by the age group.
for 10 and under (10U) teams or tournaments, the pitching distance is 35 feet from the apex of the plate to the pitching rubber.
for 12U - 15U the distance is 40 feet.
for older girls, the distance is in the process of changing. since the college and Olympic pitching distance is 43 feet, the high school distance is changing from 40 to 43 feet. different states are making the switch at different times. http://www.piaa.org/news/details.aspx?ID=1900 <<map of which states are changing when for high school.
for travel/tournament teams, the pitching distance is also changing. currently (march 6, 2010), 18U and 23U pitch from 43 feet, while 16U and under are still at 40. this is changing soon though, and the 16U teams will also pitch from 43 feet.
The distance is 50 feet.
According to the official rule book, the bases are located inside the diamond.If you were standing on the pitcher's mound, then no matter which base you look at, the measurements would be behindthe bases, because the back corners of each base is what touches the measured diamond.Home plate is measured from the point (the part that points to the catcher) to the far right corner of first base (which touches the foul line). First base to second base is measured from the foul line to the center field corner of second base, etc.
The distance from home plate to the pitcher's rubber is 46 feet.
From the apex of home to the front edge of the pitching rubber.
The distance from second base to the pitching rubber is the same as the distance from the plate to the rubber. It is 60 feet 6 inches.
