coordinate plane
a plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis
ordered pair
a pair of numbers that can be used to locate a point on a coordinate plane
quadrants
the x- and y- axes divide the coordinate plane into four regions; each region is called a quadrant
x-axis
the horizontal axis on a coordinate plane
y-axis
the vertical axis on a coordinate plane
area
the number of square units needed to cover a surface
perimeter
the distance around the outside of a figure
plane
a flat surface that extends forever
polygon
a closed plane figure formed by 3 or more line segments that intersect only at their endpoints
image
a figure resulting from a transformation
pre-image
a figure before a transformation occur
transformation
a change in the size or position of a figure
translation
a movement (slide) of a figure along a straight line
reflection
a transformation of a figure that flips the figure across a line
clockwise
the figure moves the same direction as a clock moves
counterclockwise
the figure moves the opposite direction as a clock
origin
the point where the x-axis and y-axis intersect on the coordinate plane
rotate 180 degrees
the figure turns two quadrants
rotate 270 degrees
the figure turns three quadrants
rotate 90 degrees
the figure turns one quadrant
rotation
a transformation in which a figure is turned about a point
line of reflection
a line that a figure is flipped across to create a mirror image of the original figure
line of reflection
a line that a figure is flipped across to create a mirror image of the original figure
center of rotation
The point about which a figure is rotated
intersecting lines
lines that cross at exactly one point
parallel lines
lines in a plane that do not intersect
perpendicular lines
lines that intersect to form right angles
