The triangles here are each obtained by applying rigid motions to triangle 1.
1 answer:
Rigid transformation is a transformation that does not change the measure of the side lengths and the angles.
- Triangles 3, 5 and 7 are translations of triangle 1
- Triangles 2, 4 and 6 are not translations of triangle 1
From the question (see attachment), we have the following observations
- Triangles 3, 5 and 7 have the same orientation as triangle 1
- Triangles 2, 4 and 6 are reflected versions of triangle 1
Translation and reflections are both rigid transformation.
However, when a shape is translated, the <em>resulting shape </em>must have the same orientation as the original shape.
This means that:
- <em>Triangles 3, 5 and 7 are translations of triangle 1</em>
- <em>Triangles 2, 4 and 6 are not translations of triangle 1</em>
