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

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 nonadjoining vertices of a polygon. Must be completly inside the figure


adjoining sides

sides that meet to form the angles of a figure

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.
