and 2 angles having the same measure.
(49) Scalene Triangle- a triangle with no sides having the same length
and no angles having the same measure.
(50) Acute Triangle is a triangle with 3 acute angles.
(51) Right Triangle is a triangle with 1 right angle.
(52) Obtuse Triangle is a triangle with 1 obtuse angle.
(53) Equiangular Triangle is a triangle where all three angles have the
same number of degrees.
(54) Circle-consist of a set of points each point is equidistant from a
fixed point called the center.
(55) Diameter- a line connecting two points on a circle and passing
through the circle's center. The diameter is twice the radius.
(56) Radius- a line drawn from the center of the circle to a point on the
the circle. The radius is one-half the diameter.
(57) Chord- a line connecting two points on the circle.
(58) Perimeter- is the distance around a polygon.
(59) Circumference- is the distance around a circle.
(60) Mean-is the sum of the values in a data set divided by the number
of pieces of data. Mean is the average.
(61) Median-is the middle value in a data set when the values are listed
from lowest to highest.
(62) Mode-one of the values appearing the most in a data set.
(63) Range-the difference between the lowest and the highest in a data
set.
(64) Bar Graph uses vertical and horizontal bars to display numerical
information.
(65) Line Graph often shows how data changes over time.
(66) Circle Graph shows how portions of a set of data compare with the
whole set.
(67) Pictograph ues symbols to represent data. All of the symbols have
the same value.
(68) Frequency Chart can help you list the data quickly.
(69) Line Plot shows the shape of a set of data.
(70) Interval is the amount of space between the values on a scale.
(71) The lines on which a bar graph is built are the horizontal axis and
the vertical axis.

variables, and operational symbols.

of two integers. Fractions, Mixed Numbers, Decimals, and integers are
examples of rational numbers.
(82) Irrational Numbers- are numbers that cannot be written as a
quotient of two integers. Examples are pi and square roots.
(83) coordinate plane is the plane determined by a horizontal number
line, called the x-axis, and a vertical number line, called the y-axis,
intersecting at a point called the origin. Each point in the coordinate
plane can be specified by an ordered pair of numbers. Examples (0,5),
(2,-5)
The first point or number tells us which direction to move on the x-axis,
and the second point or number tell us which direction to move on the y-
axis.
(83) Unit Fraction- is a fraction whose numerator is one and whose denominator is a whole number
greater than 1.
