24 Cards in this Set

  • Front
  • Back
the shape made with a two-band stretcher
two lines that are in the same plane that will never meet or intersect
a closed, four-sided figure with opposite sides parallel
square root
3 is an example of this when comparing it to 9
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'.
When shapes are identical, we call these shapes 'congruent'
a pair of numbers that work together to form a point. e.g., (2,4) is a point on a coordinate graph
a center point on a line
a rep-tile
tiles put together to form a larger, SIMILAR figure
PROBABILITY is the chance that something will occur. QUESTION: What is the chance that a coin will fall on the 'heads' side: ANSWER: 1 chance out of two or 50%
the distance around a polygon
a closed four-sided 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
