Will give ! the figure below shows two triangles efg and klm: two triangles efg and klm are drawn. angle kml is a right angle. the measures of the sides of the triangles are, in triangle efg, eg measures a, gf measure b, and ef measures c. in triangle klm, km measures a and ml measures b. which of the following can be used to prove that triangle efg is also a right triangle? prove that a + b is greater than c in triangle efg so c2 = a2 + b2. prove that the sum of the squares of a and c in triangle efg is greater than square of b in triangle klm. prove that kl = ef so in triangle klm a2 + b2 = c2. prove that kl = ef so in triangle klm c2 = a2 + b2, which makes triangle efg a right triangle.
