there are five ways that 2 are triangles are congruent without having to have all 6 corresponding parts congruent |
postulates = SSS, SAS ASA theorems = AAS, HL |
|
SSS (side, side, side) postulate |
if 3 sides of 1 triangle are congruent to the 3 sides of another triangle, then the triangles are congruent. |
|
SAS (side, angle, side) |
if 2 sides and the included angle of 1 angles of another triangle, then the triangles are congruent |
|
AAS (angle, angle, side) |
if two triangles and a non-included side of one triangle are congruent to two angles the corresponding non-included side of another triangle, then the triangles are congruent. |
|
HL (hypotenuse-leg) theorem |
if the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and the corresponding leg of another right triangle, then the triangle are congruent. |
|
ASA ( 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 triangle are congruent. |
