Congruent Triangles

The correspondence of the vertices of two congruent triangles can be used to specify the congruent corresponding sides and congruent corresponding angles.

\begin{array}{l} \bar{AB} ≅ \bar{GE} \\ ∠ A ≅ ∠ G \end{array}

\begin{array}{l} \bar{BC} ≅ \bar{EO} \\ ∠ B ≅ ∠ E \end{array}

\begin{array}{l} \bar{AC} ≅ \bar{GO} \\ ∠ C ≅ ∠ O \end{array}

Congruent parts of congruent triangles are usually indicated using the same line markings.
