Front

What is a translation in geometry?

Back

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

Front

If a point A has coordinates (3, 4), what are the coordinates after translating it 2 units right and 3 units down?

Front

What happens to the x-coordinate when a point is translated 4 units to the left?

Back

The x-coordinate decreases by 4.

Front

What is the effect of translating a point 0 units horizontally and 5 units vertically?

Back

The point moves 5 units up if positive, or 5 units down if negative.

Front

How do you represent a translation of a point (x, y) 3 units left and 2 units down?

Back
