# Given: △ABC with a2 + b2 = c2 and right △DEF constructed with legs a and b and hypotenuse n Prove: △ABC is a right triangle. Complete the missing parts of the paragraph proof. Proof: We are given a2 + b2 = c2 for △ABC and right △DEF constructed with legs a and b and hypotenuse n. Since △DEF is a right triangle, we know that a2 + b2 = n2 because of the . By substitution, c2 = n2 Using the square root property and the principle root, we can take the square root of both sides to get c = n. By , triangles ABC and DEF are congruent. Since it is given that ∠F is a right angle, then ∠ is also a right angle by CPCTC. Therefore, △ABC is a right triangle by
