Geometry/Congruent Triangles

Methods of Determining Congruence Two triangles are congruent if: each pair of corresponding sides is congruent two pairs of corresponding angles are congruent and a pair of corresponding sides are congruent two pairs of corresponding sides and the angles included between them are congruent Tips for Proofs Commonly used prerequisite knowledge in determining the congruence of two triangles includes: by the reflexive property, a segment is congruent to itself vertical angles are congruent when parallel lines are cut by a transversal corresponding angles are congruent when parallel lines are cut by a transversal alternate interior angles are congruent midpoints and bisectors divide segments and angles into two congruent parts
