Transformations Review

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, reflection, or dilation.

Front

What does it mean to translate a figure?

Back

To translate a figure means to slide it in a straight line from one position to another without rotating or flipping it.

Front

What is the rule for translating a point (x, y) 3 units to the right and 6 units up?

Back

(x, y) --> (x + 3, y + 6)

Front

How do you rotate a figure 90 degrees clockwise?

Back

To rotate a point (x, y) 90 degrees clockwise, the new coordinates will be (y, -x).

Front

What is the result of a transformation called?

Back

The result of a transformation is called the image.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the difference between pre-image and image?

Back

The pre-image is the original figure before a transformation, while the image is the figure after the transformation.

Front

What does it mean to rotate a figure 180 degrees?

Back

To rotate a figure 180 degrees means to turn it halfway around a point, resulting in the coordinates (x, y) becoming (-x, -y).

Front

What is the x-axis?

Back

The x-axis is the horizontal line in a coordinate plane where y = 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line in a coordinate plane where x = 0.
