Front

What is the definition of reflection in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

What is the formula for translating a point (x, y) by (a, b)?

Back

(x+a, y+b) where (a, b) is the translation vector.

Front

What is the definition of symmetry in geometry?

Back

A property where a shape is invariant under certain transformations, such as reflection or rotation.

Front

How do you determine the number of lines of symmetry in a regular polygon?

Back

A regular polygon with n sides has n lines of symmetry.
