Transformations and Similar Figures
figures with same size and shape
a pair of sides or angles in the same position on similar figures
when a figure can be folded on a given line that divides it into two congruent parts
a flip across a given line
a turn around a given point with a given angle and direction
when a figure can be turned around a central point less than 360 degrees and it matches up with the original image
a change in the size or position of a figure
movement of a figure along a straight line
have the same shape but are not the same size
a ratio used to enlarge or reduce similar figures
a transformation that changes the size of an image but not the shape.
a comparison of two numbers by division
an equation that states that two ratios are equal
a ratio of two quantities with different units
an increase in size of all dimensions in the same proportions and have a scale factor > 1
a decrease in size of all dimensions in the same proportion and have a scale factor < 1
a rate simplified so the denominator is 1 (mpg, cost/item)
used to solve proportions or compare two ratios
uses similar figures and proportions to find a missing measurement
the ratio of a distance in a drawing to the actual distance
