Answer:to Prove that KL is equal to c by Pythagorean Theorem.Step-by-step explanation:In the two triangles the triangle KLM is a right triangle with sides a and b as the two legs of the triangle .We can apply the Pythagorean Theorem to find KL.In the triangle KGF two sides are a and b .If we can prove KL=EF, then Pythagoras Theorem will be true for the triangle KGF, and therefore we can prove triangle KGF to be a right triangle.The correct option to show triangle KGF to be a triangle is to Prove that KL is equal to c by Pythagorean Theorem.
