Transformation

What is the difference between a pre-image and an image?

• A pre-image is the original shape before a transformation, while the image is the shape after the transformation.

• A pre-image is the final shape after a transformation, while the image is the original shape.

• A pre-image is a type of image that has been altered, while the image is the unchanged version.

• A pre-image and an image are the same and can be used interchangeably.

Define translation in geometry.

• Translation is a transformation that moves every point of a shape the same distance in the same direction.

• Translation is a rotation of a shape around a fixed point.

• Translation is a reflection of a shape over a line.

• Translation is a scaling of a shape to a different size.

What is the effect of translating a point (2, 3) by 3 units left and 2 units down?

• (-1, 1)

• (1, 5)

• (5, 1)

• (2, 1)

What is a rotation?

• A transformation that turns a shape around a fixed point, called the center of rotation.

• A type of movement that involves flipping a shape over a line.

• A process of enlarging or reducing a shape while maintaining its proportions.

• A method of sliding a shape from one position to another without changing its size.

How do you determine the coordinates of a point after a translation?

• Multiply the original coordinates by the translation values.

• Add or subtract the translation values from the original coordinates.

• Ignore the translation values and keep the original coordinates.

• Replace the original coordinates with the translation values.

What is reflection in geometry?

• Reflection is a transformation that flips a shape over a line, creating a mirror image.

• Reflection is a process of rotating a shape around a point.

• Reflection is a method of scaling a shape to a larger size.

• Reflection is a technique used to translate a shape to a different location.

What does it mean for figures to be congruent?

• Congruent figures have the same shape and size.

• Congruent figures have different shapes but the same size.

• Congruent figures are always larger than non-congruent figures.

• Congruent figures can be rotated but not reflected.

What is the image in a transformation?

• The image is the original shape before transformation.

• The image is the result of a transformation applied to a pre-image.

• The image is a type of geometric figure that cannot be transformed.

• The image is the process of changing the size of a shape.

What does it mean for figures to be similar?

• Similar figures have the same shape but may have different sizes.

• Similar figures are always the same size and shape.

• Similar figures have different shapes but the same size.

• Similar figures are completely unrelated in size and shape.

If a shape is rotated 90 degrees clockwise, what happens to its orientation?

• The shape turns to the left, changing its orientation.

• The shape turns to the right, changing its orientation.

• The shape remains in the same orientation.

• The shape flips upside down.
