• Arithmetic Sequence


  A series of numbers
• X-Axis - a horizontall line with infinite positive and negative integers
• Y-Axis - a vertical line with positive and negative integers
• Quadrant - the four regions formed by the intersection of x-axis and y-axis
• Coordinate Plane - a graphical representation of ordered pairs (x,y)
• Point - an exact location on the coordinate plane
• Origin - point where x-axis and y-axis intersect
• (0,0) is called origin or point of reference.
• (0,0) is called the origin.
• The vertical axis is called the y-axis.
• A point can be represented as coordinates.
• The horizontal axis is called the x-axis.
• Ordinate - the vertical distance from the origin to a given point
• Ordered Pair - a pair of numbers that represents a point on the coordinate plane
• Coordinates are numbers that represent the position of an object on a graph.
• Radius - the distance from the center of a circle to its circumference  
• Area - the amount of space inside a shape or figure
• Circumference - the distance around a circle
• Diameter - the distance across a circle through its center, twice the radius
• Circumference - the length around the edge of a circle
• Chords - line segments whose endpoints lie on a circle
• Diameter - the longest chord through the center of a circle
• Square Root - the number whose square is equal to another number
• Prime Number - a whole number greater than one which has no positive divisors other than one and itself
• Tangent - a straight line that touches a curve at one point only
• Arc - a curved portion of a circle
• Sector - part of a circular region enclosed by two radii and an arc
• Factorial - the product of all positive integers less than or equal to a given integer
• Fibonacci Sequence - a sequence of numbers where every number is the sum of the two preceding ones (1, 1, 2, 3, 5, 8...)
• Pythagorean Theorem - In any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs.
