The reason is Side-side-side triangle theorem
This theorem states that all three sides of a triangle are congruent (identical) to the corresponding sides of another triangle, then the triangles themselves are also congruent.
Hence the answer is Side-side-side triangle theorem
Solve for c by simplifying both sides of the equation, then isolating the variable.
Exact form: c = -4/9, 2
Decimal form: c = -.4, 2
