Question

question 2
which one of the following is an example of translation?

a bird flying on a straight path

the movement of hands of a clock

a person observing his image in the mirror

foot prints

Explanation:

To determine the example of translation, we recall that translation is a rigid transformation where an object moves along a straight path without rotation or reflection.

• "A bird flying on a straight path" involves moving along a straight line without rotation, so it's translation.
• "The movement of hands of a clock" is rotation (around the clock's center).
• "A person observing his image in the mirror" is reflection (mirror image).
• "Foot prints" are a result of multiple steps and not a single translation (involve contact and pressure, not a rigid motion of a single object along a straight path as a whole).

Answer:

A. A bird flying on a straight path
