Math folks, I'm trying to calculate the area of some irregularly shaped triangles. I found this formula, is it accurate? -- (link)

Base*height/2. -- nm - Shaun Jun 29, 06:54 8
- I don't know the height, nor the angles between the sides. All I know is the 3 sides. -- nm - Subversive Jun 29, 06:55 7
  - wiki says yes - Heron's formula is how you can calc. the area if you only know the sides -- (link) - Roger More Jun 29, 06:57 1
    - Thanks. -- nm - Subversive Jun 29, 06:59
  - Ok then, take 2 adjacent sides, multiply them and divide by 2. -- nm - Shaun Jun 29, 06:57 4
    - Oh whoops. That's for a right triangle. Sorry :( -- nm - Shaun Jun 29, 06:58 3
      - But you should be able to convert a triangle into 2 smaller right triangles and go from there. -- nm - Shaun Jun 29, 06:59 2
        
        you'd need to use trigonometery to calculate the shared side of the two right-angle triangles though -- nm - Roger More Jun 29, 07:01 1
        
        or algebra. -- nm - psilotum Jun 29, 07:05
