Determine the number of triangles calculator
WebDots in rectangle = n (n+1) But remember we doubled the number of dots, so Dots in triangle = n (n+1)/2 We can use xn to mean "dots in triangle n", so we get the rule: Rule: xn = n (n+1)/2 Example: the 5th Triangular Number is x 5 = 5 (5+1)/2 = 15 Example: the 60th is x 60 = 60 (60+1)/2 = 1830 WebThe formula used to find the radius is, r = sqrt [ ( ( s - a ) ( s - b ) ( s - c )) / s ], where s is the semi-perimeter of the triangle. This is the radius ( R) of the circumscribed circle of the solved triangle. The circumscribed circle is a …

WebJan 1, 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.
