Acute Angle
Any angle between 0 degrees and 90 degrees
Adjacent Angles
Angles that have the same vertex and one side in common
Angle
The shape made by two straight lines coming together at a point. The space between those two lines
is measured in degrees
Area
The surface or amount of space occupied by a two-dimensional object such as a rectangle, circle, or
square
Base
As it relates to triangles, the base is the line forming the bottom of the triangle
Bisect
To divide something into two parts that are often equal. When an angle is bisected for example, the
two resulting angles are equal
Circle
A closed curved line around a central point. A circle measures 360 degrees
Circumference
The distance around the curved line that forms the circle
Cube
A three dimensional square, with the measurements in all the three dimensions being equal
Decimal
A part of a number represented by digits to the right of a point, called a decimal point
Degree
A unit of measurement for angles
Denominator
The part of a fraction below the dividing line
Diagonal
Line drawn from one corner of a rectangle or square to the farthest opposite corner
,Diameter
The length of a straight line that crosses from one side of a circle, the rough the center point, to a
point on the opposite side. The diameter is the longest straight line you can draw inside a circle
Difference
The result of subtracting one number from another.
Digit
Any of the numerical symbols 0 to 9
Dividend
In a division problem, the number being divided is the dividend
Divisor
In a division problem, the number that is divided into another number is called the divisor
Equation
A mathematical statement that indicates the value of two mathematical expressions,
Equilateral Triangle
A triangle that has three equal sides and three equal angles
Equivalent Fractions
Fractions having different numerators and denominators but still have equal values, such as the two
fractions 1/ and 2/4
Force
A push or pull on a surface.
Formula
A mathematical process used to solve a problem
Fraction
A portion of a whole number represented by two numbers. The upper number of a fraction is known
as the numerator and bottom number is known as the denominator
Improper Fraction
A fraction whose numerator is larger than its denominator
Invert
To reverse the order or position of numbers
,Isosceles Triangle
A triangle that has two equal sides and two equal angles
Joist
Lengths of wood or steel that usually support floors, ceilings, or a roof.
Loadbearing
Carrying a significant amount of weight and/or providing necessary structural support
Mass
The quantity of matter present
Mixed Number
A combination of a whole numbers with a fraction or decimal.
Negative Number
Numbers less than zero
Numerator
The part of a fraction above the dividing line
Obtuse Angles
Any angle between 90 degrees and 180 degrees
Opposite Angles
Tow angles that are formed by two straight lines crossing. They are always equal
Perimeter
The distance around the outside of a close shape, such as a rectangle, circle, square, or any irregular
shape
Pi
A mathematical value of approximately 3.14 used to determine the area of and circumference of a
circles
Place Value
The exact value a digit represents in a whole number, determined by its place within the whole
number or by its position relative to the decimal point
Plane Geometry
The mathematical study of two-dimensional (flat) shapes
Positive Numbers
Numbers greater than zero
, Product
The answer to a multiplication problem
Quotient
The result of a division problem
Radius
The distance from a center point of a circle to any point on the curved line, or half the width
(diameter) of a circle
Rectangle
A four sided shape with four 90 degree angles.
Remainder
The amount left over in a division problem
Right Angle
An angle that measures 90 degrees.
Scalene Triangle
A triangle with sides of unequal lengths
Solid Geometry
The mathematical study of three-dimensional shapes
Square
A special type of rectangle with four equal squares and four 90-degree angles
Straight Angle
A 180 degree angle or flat line
Stud
A vertical support inside the wall of a structure to which the wall finish material is attached
Sum
The resulting total in addition problem
Triangle
A closed shape that has three sides and three angles
Unit
A definite standard of measure
