VOCABULARY ABOUT TRANSFORMATIONS

1. VOCABULARY LIST
GOAL: The student will be able to
handle the four quadrants of the co-
ordinates plane to translate, rotate
or reflect different 2D shapes or
polygons, identify the polyhedrons,
nets, faces and vertices.

2. coordinates- the unique ordered pair of numbers
associated with each point in a plane.
coordinate plane- the plane, made by the
horizontal and vertical axes, used to graph two-
dimensional objects.
ordered pair- a pair of numbers, (x, y), that
belongs to a specific point on the coordinate
plane.
origin- the meeting point of the x- and y-axes
having the coordinates of (0, 0).
translation- sliding a graph to a new position in
the coordinate plane without changing its shape.

3. Rotation: A circular movement. Rotation has a central
point that stays fixed and everything else moves around
that point in a circle.
Reflection: A transformation where each point in a shape
appears at an equal distance on the opposite side of a
given line - the line of reflection.
Transformation- moving every point of a graph the same
distance either left, right, up, down, or toward or away
from the axes.
Vertex- the point where two line segments meet.
X-intercept- the point at which a graph crosses the x-axis.
Y-intercept- the point at which a graph crosses the y-axis.
Quadrant: the four regions in a coordinate plane.
