Area/Perimeter
What is a base?
bottommost line, usually on a triangle
equilateral
equal sides, all sides of the object are the same length
what is a percent
parts per 100
<,>,=
less than, greater than, equal to
complimentary angles
two angles that measure 90 degrees
area= base*height/2
Triangle area
equation vs expression
equations show 2 sides are equal, expressions are just groups of numbers and symbols that indicate a value.
percent increase
Initial Value+(initial value)*(percent increase)=value after increase
coefficient
the number before the base of an exponent
angles in the same position when a transversal cuts across parallel lines
corresponding angles
rectangle area
length*width
what does "rate of change" mean?
slope
slope formula
m=rise/run= y2-y1/x2-x1
cubed
raised to the third power, x*x*x
Diameter vs radius
line segment that pass through circle from one point to opposite end, radius is half of that
what is the difference in area and perimeter?
perimeter= sum of the length of all sides of a geometric object
Area= measure of entire geometric object, including the inside
Tangent
touching
Least common denominator LCD
the smallest denominator 2 fractions can share
mixed number
a number consisting of a while number and a fraction, 1 1/2
hypotenuse
longest side of a right triangle
What is the Area of a circle?
πr^2
what is a number that is related to another number so that their product is equal to 1
Reciprocal
A/B=C/D, A*D=B*C. What is this term called?
Cross multiplication
least common multiple
for any given two numbers, the lowest number that has both as factors
midpoint
a point that divides a segment perfectly in half
