This allows pairs of pistons to share crank pins (a connection on the crankshaft). This firing interval is a multiple of the 60 degree V-angle, therefore the combustion forces can be balanced through use of the appropriate firing order. Because the legs are of equal length, the base angles are also identical. The most obvious are the 60 and 120 degree angles (which form the three and six sided plane figures), and the perpendicular, the 90 degree square. What is the true length of it? How many degrees are in an angle that turns through 1/2 of a circle? Because the legs are of equal length, the base angles are also identical.
