1.2 Vocabulary discovery

is the mapping (location), or movement, of a plane (where you plot points) according to a common action/movement or operation (+ or - ).

a special type of transformation that preserves the size and shape of the figure.

The original (OG, happened first, old) in a transformation

The new figure/shape created from a transformation (a form of movement)

a rigid motion transformation (keeps size and shape as it moves) that “slides” each point of a figure the same distance and direction (up, down, left, right

a rigid motion transformation that “flips” a figure across a line of reflection (example: an x-axis or a y-axis.)

a rigid motion (stays same shape and size) that turns/twists a figure on a plane about a fixed point,

an apostrophe/dash added to a point or capital letter that identifies a new location from one of the rigid motions and dilations

 points where two or more line segments or edges meet (like a corner).

sides that have the same relative positions geometric figures. So, they would be matching sides, even if the figure has gone through a form of rigid motion
