 Line a two dimensional straight path that extends in both directions without any end points. Line segments a portion of a line that has two end points parallel lines lines that never cross no matter how far they extend. They are always the same distance apart Intersecting Line Lines that cross at some point 2-dimensional a figure that has only length and width polygon a plane figure made up of 3 or more straight lines Circular base a special side of a cone or cylinder that forms a closed curve curved surface the curved region on three-dimensional surfaces straight edge the line segment formed where flat faces meet curved edge the curved line segment that forms where a curved surface meets a circular base vertex where at least three straight edges (3-d figures) or two straight lines (2D figures) come together 3-dimensional a figure that has length, width, and height plane figure any two dimensional figure cube a 3D figure with 8 vertices, 12 straight edges, 6 flat faces rectangular prism a 3D figure with 8 vertices, 12 straight sides, 3 rectangular flat surfaces. 2 triangular flat faces triangular prism a 3 D figure with 6 vertices, 6 straight edges, 3 rectangular flat faces, 2 triangular flat faces cylinder a 3 D figure with 2 curved edges, 2 circular bases, and one curved surface sphere 3D figure with one curved surface- a ball square pyramid 3D figure with 5 vertices, 8 straight edges, 4 flat faces, 1 square base rectangular pryamid 3D figure with 5 vertices, 8 straight edges, 4 flat surfaces, 1 rectangular base triangular pryamid 3D figure with 4 vertices, 6 straight edges, 4 triangular flat faces cone 3 D figure with one vertex, one curved surface, one circular base numerator part of the fraction written above the line. Represents the part of the whole denominator part of the fraction written below the line. Refers to the total number of parts into which the whole number is divided multiplicand factor being multiplied in a multiplication problem multiplier factor being mulitplied by in a multiplication problem product answer to a multiplication porblem divisor quantity by which a number is to be divided by dividend quantity to be divided quotient answer to a division problem remainder number left over when one number is divided by another multiple product of two whole numbers angle two rays or line segments that intersect or have the same endpoint right angle angle that measures exactly 90 degrees obtuse angle angle that is more that 90 degrees but less than 180 degrees acute angle angle that is less than 90 degrees but more than 0 degrees sum of all the angles in a triangle 180 degrees ray part of a line that has only one endpoint and extends indefinetly in only one direction equilateral triangle triangle having 3 sides of equal length isosoles triangle triangle having only 2 sides of equal length scalene triangle triangle having 3 sides with 3 different lengths equivalent fractions fractions that have the same value but are expressed with different numbers. 4/8 and 2/4 congruent figures figures with indenical angles and sides of equal length. they are the same shape and size perpendicular lines lines that intersect to form "square corners" or right angles (90 degrees) where they cross communtative property of addition sum remains the same when the order of addends changes commutative property of multiplication product remains the same when the order of factors is changed. quadrilateral polygon with 4 sides parallelagram quadrilateral in which opposite sides are parallel and congruent diagonal line segment connecting two non-adjoining vertices of a polygon. Must be completly inside the figure adjoining sides sides that meet to form the angles of a figure Lowest Common Multiple the multiple of two or more numbers having thee least value. Pentagon: A polygon with exactly five sides Hexagon: A polygon with exactly six sides Octagon: A polygon with exactly eight sides Histogram: a graph in which the labels for the bars are numerical intervals. Used to compare data. Line graph A diagram upon which plotted points from a set of data form a line that shows CHANGE OVER TIME. Bar graph: Uses length of solid bars to represent numbers and compare data, such as quantities. Similar: Two figures that have the same proportions but are not the same size. (same shape, different size) Congruent: Figures with identical angles and sides of equal lengths. (Same size, same shape) . Reflection: The change in location of a figure across a straight line that results in a mirror image FLIP Translation: The movement of a geometric figure without changing its appearance. SLIDE Rotation: To turn a figure around a point TURN Line of symmetry: A line that divides a figure so each half is a mirror image of the other Rotational symmetry: Property of a figure that can be rotated less than a full turn around a point and still look identical to the original figure. Order of symmetry: The number of points around which a figure can have rotational symmetry.
