Geometry Transformations Quiz

What is a transformation in geometry?

• A change in the position, size, or shape of a figure.

• The original figure before a transformation.

• The resulting figure after a transformation.

• A process of pairing points in the preimage with points in the image.

What is the term for the original figure before a transformation?

• Image

• Preimage

• Mapping

• Reflection

Which transformation preserves size and shape?

• Translation

• Rigid Transformation (Isometry)

• Vertical Shift

• Horizontal Shift

What does a translation vector describe?

• The line over which a figure is reflected.

• The flipped image of the figure.

• The distance and direction of a translation.

• Movement up or down.

What is a line of reflection?

• A directed line segment for translation.

• The line over which a figure is reflected.

• Movement left or right.

• The original figure before a transformation.

What is the definition of a line of symmetry?

• A line that divides a figure into two congruent parts.

• A line that divides a figure into two identical parts.

• A line that divides a figure into two equal parts.

• A line that divides a figure into two similar parts.

Which transformation rule represents a 90° clockwise rotation?

• (x, y) → (-y, x)

• (x, y) → (y, -x)

• (x, y) → (-x, -y)

• (x, y) → (x, -y)

What is the translation rule for transformations?

• (x, y) → (x - a, y - b)

• (x, y) → (x + a, y + b)

• (x, y) → (x, y)

• (x, y) → (x + b, y + a)

What is the dilation rule for transformations?

• (x, y) → (kx, ky), where k is the scale factor.

• (x, y) → (x/k, y/k), where k is the scale factor.

• (x, y) → (x + k, y + k), where k is the scale factor.

• (x, y) → (x - k, y - k), where k is the scale factor.

Match the transformation with the term that describes it.
