**Distance Formula CBSE NCERT solutions Chapter 7 Exercise 7.1 Question 4**

**4.** Check whether **(5, -2), (6, 4)** and **(7, -2)** are the vertices of an isosceles triangle.

**Solution:**

Let **A =** (5, -2), **B =** (6, 4) and **C =** (7, -2)

Using **Distance Formula** to find distances **AB, BC and CA**.

We can see that **AB = BC**. Therefore, **A, B and C** are vertices of an **isosceles triangle**.
