Question: In circle geometry, what is the difference between a Tangent, a Secant,
and a Chord?
✔✔ Answer: A Tangent is a line that touches a circle at exactly one point; a
Secant is a line that intersects a circle at two points; and a Chord is a line
segment with both endpoints on the circle's circumference.
Question: How is the Diameter of a circle defined?
✔✔ Answer: It is a chord that passes specifically through the center of the
circle.
Question: What is the formula for the Area of a triangle?
,✔✔ Answer: A=2Base×Height
Question: How do Plane geometry and Solid geometry differ?
✔✔ Answer: Plane geometry is 2D (flat shapes), while solid geometry is 3D
(three-dimensional objects).
Three characteristics of real numbers? -ANSWER✔✔Can be measured, has a
concrete value, can be manipulated
Integer -ANSWER✔✔a hole number that can be positive, negative, or zero
rational number -ANSWER✔✔A number or decimal that has an end point or
repeats indefinitely.
irrational numbers -ANSWER✔✔has infinite number of digits to the right of the
decimal point
improper fraction -ANSWER✔✔when the numerator is larger than the
denominator
Equilateral Triangle -ANSWER✔✔a triangle with three equal sides and three
equal angles
Isosceles Triangle -ANSWER✔✔A triangle that has 2 equal sides.
Scalene Triangle -ANSWER✔✔A triangle with no equal sides
,The three angles in a triangle ALWAYS add up to ______ degrees. -
ANSWER✔✔180
Hypotenuse -ANSWER✔✔the longest side of a right triangle
What are the order of operations? -ANSWER✔✔Parentheses, Exponents,
Multiply, Divide, Add, Subtract
associative property -ANSWER✔✔Changing the grouping of numbers will NOT
change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with
multiplication
arithmetic sequence -ANSWER✔✔a sequence in which each term is found by
adding the same number to the previous term
geometric sequence -ANSWER✔✔a sequence in which each term is found by
multiplying the previous term by the same number
absolute value -ANSWER✔✔The distance a number is from zero on a number line
pythagorean theorem -ANSWER✔✔a²+b²=c²
slope-intercept form -ANSWER✔✔y=mx+b, where m is the slope and b is the y-
intercept of the line.
midpoint formula -ANSWER✔✔(x₁+x₂)/2, (y₁+y₂)/2
, expanded form -ANSWER✔✔A way to write numbers that shows the place value
of each digit.
Percent Change Formula -ANSWER✔✔Percent Change =(final value−initial
value)/initial value×100
prime number -ANSWER✔✔A whole number that has exactly two factors, 1 and
itself.
prime factorization -ANSWER✔✔Breaking down a composite number until all of
the factors are prime
a coordinate plane goes in what direction? -ANSWER✔✔Counterclockwise
Commutative Property -ANSWER✔✔The property that says that two or more
numbers can be added or multiplied in any order without changing the result.
Associative Property -ANSWER✔✔In multiplication and addition, the way
numbers are grouped in parentheses does not matter, (a+b)+c=a+(b+c)
Binomials -ANSWER✔✔An algebraic expression with two different variables
(example: 3x+7)
Box plots -ANSWER✔✔(AKA: whisker plots) data is shown using the median
and range of a data set
