7.1 Fundamentals of Congruence

Step 1

Congruence relies on vertex order: $A \leftrightarrow F$ , $B \leftrightarrow E$ , $C \leftrightarrow D$ .

Step 2

Sides: $AB = FE$ , $BC = ED$ , $AC = FD$ .

Step 3

Angles: $\angle A = \angle F$ , $\angle B = \angle E$ , $\angle C = \angle D$ .

Final Answer

Pairs matched by vertex order.
