ok guys, this is not spam and yes i think ya'll are cute.
i have a deck that where the steps are going is a 45 degree angle. my total rise is from ground to finished height is 26 inches. i am making my finish threads @ 12 inches. so i am cutting my risers, 6.5 rise and 11 inch thread for a total of 3 treads. these will fit the two sides sq. my question is how do i compute the king tread that connects the two that is on a 22.5 degree angle from the sq. ones. strings and straight edge will work, just thought i could get and answer from here. (a sq + b sq = c sq) using 11 inch did not work. thanks, this was my first question to this forum, hope i made your day.
