Because ? abc and ? cbd both have a right angle, and the same angle b is in both triangles, the triangles must be similar by aa. likewise, ? abc and ? acd both have a right angle, and the same angle a is in both triangles, so they also must be similar by aa. the proportions and are true because they are ratios of corresponding parts of similar triangles. the two proportions can be rewritten as a2 = cf and b2 = ce. adding b2 to both sides of first equation, a2 = cf, results in the equation a2 + b2 = cf + b2. because b2 and ce are equal, ce can be substituted into the right side of the equation for b2, resulting in the equation a2 + b2 = cf + ce. applying the converse of the distributive property results in the equation a2 + b2 = c(f + e). which is the last sentence of the proof?
