Front

What is a translation in geometry?

Back

A transformation that moves every point of a figure the same distance in the same direction.

Front

What is the effect of reflecting a point (x, y) over the y-axis?

Back

The new coordinates will be (-x, y).

Front

What is the effect of reflecting a point (x, y) over the x-axis?

Back

The new coordinates will be (x, -y).

Front

What is the difference between reflection and rotation?

Back

Reflection flips a figure over a line, while rotation turns a figure around a point.

Front

If a triangle has vertices A(1, 2), B(3, 4), C(5, 6), what are the coordinates after a reflection over the x-axis?

Back

A'(1, -2), B'(3, -4), C'(5, -6).
