A tool used for graphing that is a display of a two dimensional plane. It
consists of an x-axis and a y-axis: the x-axis being a horizontal number
line, the y-axis is a vertical number line, and the axes meet at the origin.
- Correct Answer - coordinate plane
The vertical line that passes through the origin on a coordinate plane.
- Correct Answer - y-axis
A polygon with 5 sides and 5 angles.
- Correct Answer - pentagon
A transformation that produces an image that is the same shape as the
source figure but a different size. These enlarge or reduce a polygon by
a specific scale factor in relation to a given center point.
- Correct Answer - dilation
The quality of having the same shape on either side of a central line. In
data analysis, the quality of the data having the same shape on both
sides of the mean. - Correct Answer - symmetry
,A change to the orientation of a shape.
- Correct Answer - transformation
Two figures have this property if they have the same shape but not
necessarily the same size.
- Correct Answer - similar
Two numbers written in the form (x, y), where x represents the x-value or
x-coordinate, and y represents the y-value or y-coordinate.
- Correct Answer - ordered pair
A shape which has the property that if it is reflected about a line, the two
sides will be identical. - Correct Answer - reflective symmetry
A transformation that moves a source figure in a specified direction for a
specified distance. - Correct Answer - translation
The ratio of sides of two similar geometric figures.
- Correct Answer - scale factor
, An image in which every point is the same distance from a line as a
corresponding point on the opposite side of the line. - Correct Answer -
reflection
A true statement in which two ratios are equal to each other. - Correct
Answer - proportion
In translations on the coordinate plane, this is the figure that results from
the transformation. - Correct Answer - image
A formula for calculating the distance between two coordinates. - Correct
Answer - distance formula
A line directly in the middle of two reflected images. All reflected points in
the images are the same distance from this line as one another. -
Correct Answer - line of reflection
A mark used to indicate images are the same even after transformations.
- Correct Answer - prime mark
The four sections of the coordinate plane, separated and defined by the
x-axis and y-axis. - Correct Answer - quadrants
