Answer : 161700 ✔️
Solution :
As we know that :
A triangle has 3 vertices and as given in the question that there are 100 points in circle.
So, according to the formula of combination :
nCr = n!/!r.(n-r)!
Here, n = 100 and r = 3
=> 100!/3!(100-3)!
=> 100!/3!.97!
=> 100×99×98×97!/3×2×1×97!
=> (100×99×98)/6
=> 161700
So, 161700 right angle triangles can be drawn through 100 points on a circle.
I hope it will be helpful for you ☺️
