slope		matching sides of 2 or more polygons
corresponding angles		figures with the same shape but not necessarily the same size are similar
scale		ratios that name the same comparison
quadrant		a rate in which the 2nd quantity in the comparison is 1 unit
y-axis		the technique of using similar figures and proportions to find a measure
similar		angles in the same position formed when a third line intersects 2 lines
cross product		the product of numbers on the diagonal when comparing 2 ratios
scale drawing		the point where the x-axis intersect on the coordinate plane (0,0)
coordinate plane		an equation that states that 2 ratios are equivalent
scale factor		a proportional model is a 3-dimensional object
Indirect measurement		a drawing that uses a scale to make an object smaller than or larger than the real object
origin		the vertical axis on a coordinate plane
corresponding sides		a ratio that compares 2 quantities measured in different units
unit rate		the horizontal axis on a coordinate plane
rate		a plane formed but he intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis
scale model		the ratio between 2 sets of measurements
x-axis		a pair of numbers that can be used to locate the point on a coordinate plane
proportion		a measure of the steepness of a line on a graph; the rise divided by the run
ordered pair		the x- and y-axises divide the coordinate plane into 4 regions.
equivalent ratios		the ratio used to enlarge or reduce similar figures
