    Given: ΔABC is a right triangle. Prove: a2 + b2 = c2 The two-column proof with missing justifications proves the Pythagorean Theorem using similar triangles: Statement Justification Draw an altitude from point C to Line segment AB Let segment BC = a segment CA = b segment AB = c segment CD = h segment DB = x segment AD = y y + x = c c over a equals a over y and c over b equals b over x a2 = cy; b2 = cx a2 + b2 = cy + b2 a2 + b2 = cy + cx a2 + b2 = c(y + x) a2 + b2 = c(c) a2 + b2 = c2

    SSS theorem would be used to prove s triangles are congruent, are we proving that here @Moo_Moo17 ?

    it looks like it would be a good answer knowing that the triangle looks likes its a right angle triangle

    That is true but the answer is not right because we "NEVER" use "PIECES" of a theorem, we use the whole theorem or we don't use it at all. :P

    ^-^ ok so with tht one crossed out would it be B since i think the triangle is SSS

    Nah if you look at the two column proof Addition Property of Equality work is done .

    C was done in the problem too because B2=cx cx is enter in the place of b2
