1. which triangles are not translations of

triangle 1?
the triangles here are each obtained by applying rigid
motions to triangle 1.
the odd triangles
the triangles from 5 through 11.
all of the triangles
the triangles from 2 through 7
the even triangles
the triangles from 9 through 15

Explanation:

Translation is a type of rigid motion where a figure is moved without rotation or reflection. Looking at the triangles, the even - numbered triangles (2, 4, 6, 8, 10, 12, 14) are reflections (not translations) of triangle 1. Rigid motions include translation, rotation, and reflection. Since the question asks for non - translations, and the even - numbered triangles are reflections (a different type of rigid motion from translation).

Answer:

The even triangles
