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

Explanation

To determine whether the points \( (5, -2) \), \( (6, 4) \), and \( (7, -2) \) are the vertices of an isosceles triangle, we need to calculate the lengths of the sides formed by these points. We will use the distance formula, which is given by:

\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]

Let’s denote the points as follows:
- \( A(5, -2) \)
