 Two figures with the same shape and size.  over there, there’s two triangles exactly the same but moved to different places. 

 If the relative position of two figures/angles/sides is same in two figures, then they are called corresponding figures/angles/sides.

 Given an equation between two fractions or rational expressions, one can cross- multiply to simplify the equation or determine the value of a variable.

 Cross-products can be used for three purposes: to compare fractions, to determine whether a proportion is true, and to solve a proportion. You can use cross- products as a shortcut method to find whether two fractions are equivalent. If the cross-products are equal, then the fractions are equivalent; if the cross-products are not equal, then the fractions are not equivalent.

 Enlargement is when you make a shape bigger without changing the shape of it.  I made that book bigger by enlarging the size.

 An equivalent rate is multiple rates in different forms that have the same outcome.

 Different ratios that have the same meaning.

 Two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one.

 A proportion is simply a statement that two ratios are equal.

 A unit rate is a ratio that has a denominator of 1. A unit rate is also called a unit ratio. (There the same thing.)

 A proportion is a name we give to a statement that two ratios are equal.

 In math, a rate is a ratio between two measurements, often with different units.

 A table that shows the amount of something and the cost.

 In math, a ratio is a relationship between two numbers of the same kind.

 Reduction is when you reduce a number to a different form.

 Figures are similar if the are alike in shape, size, or color.

 Polygons are similar if they are alike in shape, size, or color.

 Size change factor is when you change the size of a figure.
