Theorem 6.3 →


AB/DE = AC/DF [why]


Similarly, AB/DE = BC/EF और


AB/DE = BC/EF = AC/DF



If two angles of a triangle are respectively

equal to two angles of another triangle,

then by the angle sum property of a triangle their third angles will also be equal.

Therefore A A A [ angles ] similarity criterion can also be stated as follows:
