Congruency
|
- Same shape and size
- Fit exactly on top of each other |
|
|
Reflected
|
Mirror image
E.g. The {shape} has been reflected along the {horizontal or vertical} axis |
|
|

SSS
(Side, Side, Side) |
Triangles are congruent if the three sides on one triangle are the same length as the matching sides on the other triangle
|
|
|
SAS
(Side, Angle, Side) |
Triangles are congruent if two sides and the included angle are the same size as the matching sides on the other triangle
|
|
|
ASA
(Angle, Side, Angle) |
If two angles and a side in one triangle are the same size as the matching two angles and side on the other, the triangles are congruent
|
|
