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 distance formula used to calculate the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

How does reflecting a point over the Y-axis affect its coordinates?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Back

(5, 2)

Front

What happens to the coordinates of a point when it is reflected over the X-axis?

Back
