Explanation:

In geometry, an equilateral triangle has all sides equal, and by the angle - side relationship, its three angles are congruent (each 60 degrees). The if - then form separates the hypothesis and conclusion. The negation is the opposite statement.

Answer:

The statement is True.
The statement in if - then form is: If a triangle is equilateral, then it has three congruent angles.
The negation of the statement is: There exists an equilateral triangle that does not have three congruent angles.
