Translation Practice

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a figure in a straight line from one position to another without changing its shape or size.

Front

What does the rule (x, y) → (x + 3, y + 4) represent?

Back

It represents a translation of a figure 3 units to the right and 4 units up.

Front

If point A is at (2, 3) and is translated 1 unit left and 2 units down, where is point A'?

Back

Point A' is at (1, 1).

Front

What does it mean for two figures to be congruent after a translation?

Back

It means that the two figures have the same shape and size, even though they may be in different positions.

Front

How do you translate a point 5 units to the left?

Back

You subtract 5 from the x-coordinate of the point.

Front

What is the effect of translating a figure on the coordinate plane?

Back

The figure moves to a new location without changing its size or shape.

Front

If a point (x, y) is translated to (x + 4, y - 2), what direction is it moved?

Back

It is moved 4 units to the right and 2 units down.

Front

What is the translation rule for moving a point 3 units down?

Back

The rule is (x, y) → (x, y - 3).

Front

What happens to the coordinates of a point when it is translated 2 units up?

Back

The y-coordinate increases by 2.

Front

If point B is at (0, 0) and is translated 3 units right and 1 unit up, where is point B'?

Back

Point B' is at (3, 1).
