### Non Collinear Points:

**Question:**

There are 7 non-collinear points. How many triangles can be drawn by joining these points?

**Option A):**

35 **Option B):**

7**Option C):**

8**Option D):**

10

**Correct Answer is Option A):**

35

**Explanation:**

A triangle is formed by joining any three non-collinear points in pairs.

There are 7 non-collinear points.
