Study Notes
Triangle Congruence: ASA and AAS
- ASA (Angle-Side-Angle) indicates triangles are congruent when two angles and the included side are equal.
- AAS (Angle-Angle-Side) indicates congruence when two angles and a non-included side are equal.
Triangle Mappings
- Translation and rotation can map congruent triangles when corresponding vertices align through these transformations.
- Reflection combined with translation can also map congruent triangle pairs, altering their orientation but maintaining size and shape.
- Two reflections can create a congruence transformation that preserves orientation and position.
Congruence Confirmation
- Triangles are confirmed congruent if they satisfy the conditions of ASA or AAS congruence criteria.
Rigid Transformations
- Rigid transformations include translations, rotations, and reflections, maintaining the congruency of shape and size.
- For example, mapping triangle JKL to MNQ involves a translation of vertex L to vertex Q, followed by a rotation about point L.
