Name three types of rigid transformations.

• Expansion, compression, shearing

• Translation, rotation, reflection

• Twisting, bending, warping

• Dilation, contraction, stretching

• True

• Partially true

• False

What is the formula for a translation in two dimensions?

• (x, y) → (x - a, y - b)

• (x, y) → (x * a, y * b)

• (x, y) → (x / a, y / b)

• The formula for a translation in two dimensions is (x, y) → (x + a, y + b), where (a, b) is the translation vector.

What is the difference between a translation and a dilation?

• A translation is a transformation that changes the size of a figure, while a dilation is a movement of a figure from one location to another

• A translation is a movement of a figure from one location to another without changing its size, while a dilation is a transformation that changes the size of a figure without changing its shape.

• A translation changes the shape of a figure, while a dilation changes its location

• A translation only changes the size of a figure, while a dilation changes both size and shape

What is the difference between a reflection and a rotation?

• A reflection moves an object to a different location, while a rotation keeps it in the same place.

• A reflection stretches an object, while a rotation shrinks it.

• The main difference is that a reflection flips an object over a line, while a rotation turns an object around a point.

• A reflection changes the color of an object, while a rotation changes its shape.
