For the first reason, c^2 = (a^2 + b^2) but (a^2 + b^2) = f^2, so c^2 = f^2 by the Transitive Property of Equality For the second reason, you have to know the triangle congruence postulates. SSS Postulate ---------------- Note: Take a look at the same flow proof with a different missing reason. http://openstudy.com/study#/updates/4fad7f29e4b059b524f922b9
