Document Summary

Congruent polygons - polygons whose corresponding parts(sides+angles) are congruent. Two polygons are congruent if their corresponding sides and angles are congruent. Congruent triangle postulates - are to be used to prove triangle congruence with congruent corresponding parts. Sss - if 3 sides of one triangle are congruent to 3 sides of another triangle, then the triangles are congruent. Sas - if 2 sides & the included angle of one triangle are congruent to 2 sides & the included angle of another triangle, then the triangles are congruent. Asa - if 2 angles and the included side of a triangle are congruent to 2 angles & the included side of another triangle, then the triangles are congruent. Corresponding parts of congruent triangles are congruent. You can use these four postulates/theorems to prove triangle congruence^^ Isosceles triangle theorem - if two sides of a triangle are congruent, then the angles opposite those sides are congruent.
