Geometric Transformations Reflection and Translation

A reflection ____________________.

• turns a figure around a point.

• slides an object form one place to another.

• flips or mirrors an object across a line.

• changes the size of an object.

A type of transformation where a geometric figure slides horizontally, vertically, or both.

• dilation

• translation

• rotation

• reflection

Is the picture being reflected in the y-axis or x-axis?

• y-axis

• x-axis

Rotations, Reflections and Translations are known as _________.

• Similarity Transformations

• Rigid Transformations

• Resizing Transformations

The following is a ...

• Translation

• Reflection

• Rotation

• Dilation

Determine how to translate triangle A'B'C' to triangle ABC.

• (x+2, y-5)

• (x+2, y-9)

• (x-2, y-9)

Select all transformations that result in a CONGRUENT image.

• translation, then dilation of 2

• translations up 2, then translation right 4

• vertical translation, then reflection over the x-axis

• reflection over the x-axis, then dilation of 1/2

• dilation of 3, then rotation 90 degrees counter-clockwise

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)

• (x, y) → (x - 2, y + 3)

• (x, y) → (-x, -y)

• (x, y) → (x + 2, y - 3)

Rotations, Reflections and Translations are known as _________. These transformations create CONGRUENT images that are the same size and shape.

• Similarity Transformations

• Rigid Transformations

• Resizing Transformations
