image

the shape made with a twoband stretcher


parallel

two lines that are in the same plane that will never meet or intersect


parallelogram

a closed, foursided figure with opposite sides parallel


square root

3 is an example of this when comparing it to 9


ratio

comparison of two similar things (quantities) that tells the scale between them usually written as a fraction (one number divided by another number)


complementary angles

pairs of angles whose measures add up to 90 degrees


corresponding angles

angles of two different figures that are in the same, relative position


scale factor

a number used to multiply the sides of a figure to stretch or shrink it


corresponding sides

sides of two different figures that are in the same, relative position


angle measure or the unit of measure for an angle

An angle is measured with the unit called a degree. A 'right angle' is a total of 90 degrees.


equivalent ratios

ratios written as fractions that have the same value; e.g. 1/2 is a ratio and 2/4 is a ratio; and these two ratios are equal or 'equivalent'.


congruent

When shapes are identical, we call these shapes 'congruent'


coordinate

a pair of numbers that work together to form a point. e.g., (2,4) is a point on a coordinate graph


midpoint

a center point on a line


a reptile

tiles put together to form a larger, SIMILAR figure

perimeter

the distance around a polygon


quadrilateral

a closed foursided figure


supplementary angles

two angles whose measures add up to 180 degrees


a dimension

the length and width of a polygon is called DIMENSION


to square a number

multiplying a number times itself gives you that number's SQUARE


similar shapes

shapes that have a scale factor, and the same angles and the same shape


a tessellation

a pattern that is repeated to completely cove all spaces in a flat surface


a transformation

something that has been changed
