GEOMETRY: Deriavation Of Triangle

GEOMETRY I'M GOING TO PROMOTE, I can't put the sub, I just use a notepad friend. How are geometry formulas derived? A = 1 / 2bh where b-base h-height Acute triangle area? when you say acute triangle all sides are equal, it is pure 60 ° angle. A = 1 / 2bh 👈 here we will get that Let b = 1/2 (s) bkit ganun? divided in the middle A = 1/2 {s) (1/2) (s) thus, A = 1/4 (s ^ 2) when you use algebra. Equilateral area, Equilateral area means equilateral 2 long legs are equal but the base is not. A = 1 / 2bh 👈 here we will take nyan again, area of ​​scalene triangle paps discription of equilateral triangle. A-area a-slant b-base h-height sol'n: use phytagorean theorem, to get the height h = squareroot (a ^ 2-b ^ 2) so, A = 1 / 2b [squareroot (a ^ 2-b ^ 2)]
