The other way to prove ED=EF is join AD.From this we can observer that AED and AFD are two congruent triangles because AD is the common side.angle DAE= angle DAF (same vertex A). and AE=AF (already proved).Hence by SAS we can say the two triangles are congruent.Implies sides ED and EF are corresponding sides,hence Proved :) • The 5 ways to prove congruent triangles (SSS, SAS, ASA, AAS, HL) • The 2 ways that are NOT appropriate to prove congruence (AAA, SSA/ASS) • The order of the letters matter when writing congruence statements • How to setup a geometric proof (most often in a two-column proof)
