Reflection and Distance on Coordinate Plane

Front

What is reflection in the coordinate plane?

Back

Reflection in the coordinate plane is a transformation that flips a figure over a line, creating a mirror image.

Front

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

Back

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

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²) or for points on a number line, Distance = |x2 - x1|.
