how many triangles can be drawn using 5 given points on circumference trinalge

1 answer

Assuming that the 5 given points are distinct and non-collinear, we can form triangles by connecting any three of the points.

Using the combination formula, we can find the number of ways to choose 3 points from 5:

${5 \choose 3} = \frac{5!}{3!2!} = 10$

Therefore, we can draw 10 different triangles using 5 given points on a circumference.
