Question

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


1.Which triangles are translations of triangle 1? Explain how you know.


2.Which triangles are not translations of triangle 1? Explain how you know.

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
