Question
Since the three triangles are similar, the ratio of the lengths of the corresponding sides of the largest and smallest triangles can be written as a/c = e/a, and the ratios of the lengths of the corresponding sides of the largest and second largest triangles can be written as ______. Using the Cross Products Property, these can rewritten as a2= ce and _______. Then, by using substitution, a2 + b2=ce + cf. By factoring, a2 + b2= c (e+f). Next, by looking at the original triangle, (e+f) =c. Lastly, by using substitution, a2+b2=c (c)=c2.
