there are 10 non-collinear points in a plane. by joining them how many triangles can be made?

Dear student
A triangle is formed by joining any three non-collinear points in pairs.
There are 10 non-collinear points.
The number of triangles formed
=$$\begin{gathered} {}^{10}{\mathrm{C}}_3 \\ =120 \end{gathered}$$
