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

 when two figures are (a)   , the ratios (side over side like a fraction/division) of their Corresponding side lengths are equal

can be thought of as 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.

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

is a flat surface (x and y axis/lines). It has infinite (goes on forever)  length and width, but no depth (not 3 dimensional). A plane extends infinitely in all directions in two dimensions. Planes are determined by a minimum of 3 points, but are usually named/labeled using one uppercase letter (any one letter in the alphabet).

is the relative arrangements of points after a transformation or after traveling around a geometric figure. Orientation is sorted into clockwise and counterclockwise in terms of how the points align. Reverse orientation means that the points are opposite of the original shape

(a)   in shapes are the points where two or more line segments or edges meet (like a corner). The singular of vertices is vertex. For example, a cube has 8 vertices and a cone has one vertex. Vertices are sometimes called corners but when dealing with 2d and 3d shapes, the word vertices is preferred.
