Step-by-step explanation:

hope its help huhuhuh

Answer:

Since no three points are collinear in the plane,a triangle can be formed by selecting any three point. So total number of triangles = number of ways of selecting 3 points from the given set of points.

Therefore total number of triangles = 10C3 (10)/( 3! 7) = (10*9*8)/(3*2*1) = 10*3*4=120.
