Translations

Front

What is a translation in geometry?

Back

A transformation that slides a geometric figure horizontally, vertically, or both without changing its shape or size.

Front

What is the rule for translating a point (x, y) to the right by 2 units and down by 1 unit?

Back

(x + 2, y - 1)

Front

If point A(2, 3) is translated according to the rule (x, y) --> (x + 3, y - 2), what are the coordinates of A'?

Back

A'(5, 1)

Front

What is the image in a transformation?

Back

The result of a transformation, representing the new position of a geometric figure.

Front

How do you translate a figure 5 units to the right and 3 units up?

Back

Use the rule (x + 5, y + 3).

Front

What is the pre-image in a transformation?

Back

The original figure before any transformation is applied.

Front

If trapezoid ABCD is translated 4 units to the left and 2 units down, what is the translation rule?

Back

(x - 4, y - 2)

Front

What type of transformation is a translation?

Back

A rigid transformation that preserves the shape and size of the figure.

Front

If point B(1, 2) is translated to B'(4, 5), what is the translation rule?

Back

(x + 3, y + 3) because B moves 3 units right and 3 units up.

Front

What happens to the coordinates of a point when it is translated 6 units down?

Back

The y-coordinate decreases by 6.
