Equilateral Triangle Checker

Equilateral Triangle Checker

Given the coordinates of three points, determine whether they form an equilateral triangle. An equilateral triangle is one where all sides are equal in length.

You can compute the distance between two points \( (x_1, y_1) \) and \( (x_2, y_2) \) using the formula:

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

Take care of floating-point arithmetic when performing equality comparisons; a small tolerance should be used.

inputFormat

The input consists of three lines. Each line contains two space-separated floating-point numbers representing the coordinates \( x \) and \( y \) of a point.

outputFormat

Output a single line containing true if the points form an equilateral triangle, and false otherwise.
