u can solve this question using combinations. a triangle is formed by joining three points. so find the number of ways in which u can select 3 points from 26 points which is 26 c 3 =2600 . if u dont understand the term 26 c 3 ..refer to chapter named permutations and combinations in mathematics

4,320° is.
90 x (2 x 15 - 4) ie 90 x 26 = 2340o. The sum of the interior angles of an n-sided polygon always is 90 x (2n - 4) degrees
The formal name is icosihexagon. Most people, including mathematicians, will use 26-gon since that effectively communicates the size of the polygon. But, if you want to appear pretentious or be obfuscatory, by all means use the Greek prefices.

Each exterior angle is 360/26 = 13.846 degrees approx. So each interior angle = 180-13.846 = 166.154 degrees (approx).
