Question

The triangles here are each obtained by applying rigid motions to triangle 1.

Answer 1

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 resulting shape must have the same orientation as the original shape.

This means that:

• Triangles 3, 5 and 7 are translations of triangle 1
• Triangles 2, 4 and 6 are not translations of triangle 1
