+title: Coded triangle numbers
+url: http://projecteuler.net/problem=42
+
+desc: |
+    The nth term of the sequence of triangle numbers is given by, tn = 0.5n(n+1); so the first ten triangle numbers are:
+    1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...
+    By converting each letter in a word to a number corresponding to its alphabetical position and adding these values we form a word value. For example, the word value for SKY is 19 + 11 + 25 = 55 = t10. If the word value is a triangle number then we shall call the word a triangle word.
+    Using words.txt (right click and 'Save Link/Target As...'), a 16K text file containing nearly two-thousand common English words, how many are triangle words?
