Definitions

Hypotenuse the side opposite the right angle
Acute Triangle triangle that has three acute angles
Right Triangle Triangle with one right angle
obtuse triangle triangle that has one obtuse angle
equilateral triangle triangle that has three congruent sides
Isosceles triangle triangle that has at least two congruent sides
scalene triangle triangle that has no congruent sides
equiangular triangle a triangle that has 3 congruent angles
180 degrees The sum of the angles of a triangle
acute less than 90 degrees
obtuse more than 90 degrees, but less than 180 degrees
polygon a closed plane figure whose sides are segments that intersect only at their end points
regular polygon all sides and all angles have the same measure
convex a polygon in which a line segment lies completely within the polygon
concave a polygon that is not convex
pentagon a five-sided polygon
Hexagon a six-sided polygon
heptagon a seven-sided polygon
octagon an eight-sided polygon
nonagon a nine-sided polygon
decagon a ten-sided polygon
elevenagon an eleven-sided polygon
quadrilateral a four-sided polygon
trapezoid a quadriladeral with exactly one pair of parallel sides
parallelogram a quadriladeral with both pairs of opposite sides parallel
rhombus a parallelagrom with four congruent sides
rectangle a parallelagram with four right angles
square a parallelagram with four congruent sides and four congruent angles
360 degrees sum of the angles of a quadrilateral
area of a parallelagram formula A= base x height
area of a trapezoid formula A= 1/2(b1 + b2)h
circle all the points in a plane that are the same distance from a fixed point; not a polygon
center the fixed point in the middle of the circle
radius the difference between the center and any point on the circle
diameter the distance across the circle THROUGH THE CENTER
circumference the distance around the circle
pi the ratio of a circle's circumference to its diameter for any circle
circumference of a circle formula C=pid OR C=2pi*r
Area of a circle formula A= pi*r squared
Pythagorean theorem a squared + b squared = c squared
Interior Angle An angle inside of the polygon
Exterior Angle An angle outside of the polygon
(n-2) * 180 Measurement of all interior angles of a Convex polygon
(n-2) * 180 / n Measurement of each interior angle of a regular polygon
Regular polygon Sides are congruent and angles are congruent
Foil Method in multiplying binomials First, Outer, Inner, Last
Complementary angles Two angles whose sum is 90 degrees
Supplementary angles Two angles whose sum measures 180 degrees
Verticle angles When two lines intersect at one point, the angles that are opposite eachother are these angles; These angles are congruent.
Hypotenuse The longest measurement in a right triangle
Legs The sides of a right triangle that form the right angle
Dodecagon A twelve-sided polygon
when you find the area When is the unit squared?
Transversal A line that intersects two or more lines at different points
Corresponding angles Two angles that are in the same postion on different lines intersected by a transversal; They are congruent.
Interior angleS Angles that lay inside the parallel lines
Exterior angleS Angles that lay outside the parallel lines
Alternate interior angles Angles that lay inside the parallel lines and are on opposite sides of the transversal; They are congruent.
Alternate exterior angles Angles that lay outside the parallel lines and are on opposite sides of the transversal; They are congruent.
Polynomial A sum of monomials
Term Each mononial in a polynomial is a ______.
Binomial Has two terms
Trinomial Has three terms
Standard form This is written when the terms are arranged so that the degree of each term decreases (Written according to exponential value from greatest to least)
Slope intercept form/ Function form y= mx + b
Formula for slope m= Y2-Y1 over X2-X1 OR m= rise over run
Negative reciprical When finding PERPENDICULAR slope, use the _______ ________.
Input The first number in a set of coordinates (AKA the domain and X)
output The second number in a set of coordinates (AKA the range and Y)
Domain All of the inputs
Range All of the outputs
x- intercept The place/ coordinate where the line crosses the x axis/ horizontal axis
y-intercept The place/ coordinate where the line crosses the y axis/ vertical axis
Slope The steepness of a line (How steep the line is)
Relation A group of inputs and outputs (A group of coordinates) that can be graphed
zero The x coordinate is always _______ when you are finding the y intercept.
