 1. Corresponding Parts! Two triangles are congruent if and only if thier vertices can be matched up so that corresponding parts of the triangles are congruent. 2. SSS Postulate! SSS postulate(side-side-side)-If three sides of one triangle are congruent to all three of another then the triangles are congruent. 3. SAS Postulate! SAS postulate( side-angle-side)- If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. 4. ASA Postulate! ASA postulate(angle-side-angle)-If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. 5. Isosceles Triangle Theorm! If two sdies of a triangle are congruent then the angles opposite those sides are congruent. 6. Isosceles Triangle Theorm#2 If two angles are congruent then the sides oppostie those angles are congruent 7. Isosceles Classification! Isosceles triangles have to have at least two sides congruent 8. AAS Theorm AAS Theorm( angle-angle-side)-If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle the the triangles are congruent 9. HL Theorm HL Theorm(hypotenuse leg)-If the hypotenuse and a leg of one right triangle are congruent to the corresponding parts of another right triangle then the triangles are congruent
