congruence transformations | occurs when a slide | flip | or turn of a triangle does not change the size or shape |
included angle | angle formed by two sides of a triangle | ||
SSS Postulate | If the sides of one triangle are congruent to the sides of another triangle | then the two triangles are congruent. | |
SAS Postulate | If two sides of a triangle and their included angle are congruent to two sides of another triangles and their included angle | then the triangles are congruent. | |
included side | the side between two angles of a triangle | ||
ASA Postulate | If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle | then the two triangles are congruent. | |
