Distance & Reflection Coordinate Plane Flashcard

Front

What is a reflection in the coordinate plane?

Back

A 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 across the x-axis?

Back

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

Back

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

Front

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

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

If point A is at (3, 4), what are the coordinates of A' after reflecting across the x-axis?

Back

(3, -4)
