An inverse statement is formed by negating both the hypothesis and the conclusion of a conditional statement. For example, if the original conditional statement is "If P, then Q," the inverse is "If not P, then not Q." Inverse statements can help analyze the truth values of the original statement and its contrapositive, but they are not logically equivalent to the original statement.
That may vary. The only requirement for being called "isosceles triangle" is that two of the angles are congruent. (This is equivalent to the statement that two of the sides are congruent.)That may vary. The only requirement for being called "isosceles triangle" is that two of the angles are congruent.

In mathematics, an inequality is a statement about the relative size or order of two values.
a statement that the values of two mathematical expressions are equal (indicated by the sign =)
