Unit 3: Transformations Vocabulary Practice

The angle of rotation is the point in which a figure is rotated around.

• True

• False

The center of rotation is the number of degrees a figure rotates.

• True

• False

A translation vector is a vector that gives the length and direction of a particular translation.

• True

• False

Transformations are changing a figure using translation (slide), reflection (flip), rotation (turn), and dilation (resize).

• True

• False

Line of symmetry is a line that a figure is flipped across to create a mirror image of the original pre-image figure.

• True

• False

• translation vector

• dilation

a transformation that "flips" a figure over the line of reflection
