Transformations and Translations in Geometry

Front

What is a translation in geometry?

Back

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

Front

How does a translation affect the coordinates of a point?

Back

A translation changes the coordinates of a point by adding or subtracting values from the x and/or y coordinates.

Front

If point A (2, 3) is translated using the rule (x + 4, y - 2), what are the coordinates of A'?

Back

(6, 1)

Front

What is the effect of translating a figure 5 units to the right?

Back

The x-coordinates of all points in the figure increase by 5.

Front

What is the effect of translating a figure 3 units down?

Back

The y-coordinates of all points in the figure decrease by 3.

Front

What is a rigid motion in geometry?

Back

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

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size.

Front

If point B (1, 2) is translated 2 units left and 3 units up, what are the coordinates of B'?

Back

(-1, 5)

Front

What is the x-coordinate affected by when translating a figure left or right?

Back

The x-coordinate is affected by movement left and right.

Front

What is the y-coordinate affected by when translating a figure up or down?

Back

The y-coordinate is affected by movement up and down.
