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

 is a rigid motion that “slides” left right for the value of x, and up down for the value of y.

a rigid motion (stays the same shape and size) that turns/twists a figure on a plane about a fixed point, called center of rotation, through a given angle, called the angle of rotation/

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

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

the mathematician's way of saying “I believe that this is true, but I have no proof yet”. A conjecture is a good guess or an idea about a pattern.

4 quadrants on a coordinate plane divided up by the x and y axis. The upper right quadrant is the first quadrant, then to find the 2nd, 3rd, and 4th quadrant, count to the left (counterclockwise) about the origin on each divided section.

in shapes are the points where two or more line segments or edges meet (like a corner).

Figures that have the same size and shape are congruent (equal, same) figures. If two figures are congruent, all corresponding sides and all corresponding angles have the same measure.

a specific direction or order that the angles or sides of  figures are going in alphabetical or specific order
