Formula to find number of triangles
WebJan 31, 2024 · A triangle is one of the most basic shapes in geometry. The best known and the most straightforward formula, which almost everybody remembers from school, is: area = 0.5 * b * h, where b is the length of the base of the triangle, and h is the height/altitude of the triangle. However, sometimes it's hard to find the height of the triangle. WebJan 26, 2024 · This formula allows you to mathematically divide any polygon into its minimum number of triangles. Since every triangle has interior angles measuring 180°, multiplying the number of dividing triangles times 180° gives you the sum of the interior angles. S= (n-2)\times 180° S = (n − 2) × 180°. S = sum of interior angles.
