and
v = ce. By the Addition Property of Equality
e
a
v and
By the cross-product property, a =
As similar triangles have proportional sides, we can write the proportions
f + e, therefore, we can substitute and arrive at the statement
a? + b2
cf + ce. Factoring allows the equivalent expression, a? +b² = c (f+e). By the Subtraction Property of Equality
a? + b2
