1 in everyday language, describe what a translation is

2 in everyday language, describe what a reflection is

3 in everyday language, describe what a rotation is

4 in everyday language, describe what a rotational symmetry is

Explanation:

Question 1

A translation in everyday language is moving a shape or object from one place to another without rotating it or changing its size/shape. Like sliding a book across a table—same orientation, just new position.

A reflection in everyday terms is like a mirror image. If you flip a shape over a line (like a mirror), the reflected shape is a mirror copy—same size/shape, reversed across the line (e.g., your reflection in a mirror or a butterfly’s wings being mirror images).

A rotation in everyday language is turning a shape or object around a fixed point (the center of rotation). Like spinning a top around its tip, or turning a doorknob— the object rotates around a point, changing its orientation but not size/shape.

Answer:

A translation is sliding a shape/object to a new position without rotating, resizing, or changing its shape (e.g., moving a book on a table).
