Can anyone help me? The figure below shows triangle NRM with r2 = m2 + n2: Triangle NRM has legs m and n, and r is the length of its longest side. Ben constructed a right triangle EFD with legs m and n, as shown below: Triangle EFD has legs m and n and hypotenuse f. He made the following table to prove that triangle NRM is a right triangle: Statement Reason 1. r2 = m2 + n2 Given 2. f2 = m2 + n2 Pythagorean Theorem 3. f2 = r2 Substitution 4. f = r Square Root Property of Equality 5. Triangle NRM is congruent to triangle EFD SSS Postulate 6. Angle NRM is a right angle ? 7. Triangle NRM is a
