Web1 jan. 2024 · Since a triangle is determined by the 3 straight lines forming its sides, the number of triangles is at most ( 5 3). Since each pair of line segments intersects and all the intersections are distinct, each set of 3 lines determines a triangle, so the number of triangles is exactly ( 5 3) = 10. Share Cite Follow edited Jan 1, 2024 at 3:26 WebThese triangle formulas can be mathematically expressed as; Area of triangle, A = [ (½) b × h]; where 'b' is the base of the triangle and 'h' is the height of the triangle.
