| Question | Answer |
|---|---|
| angle | a geometric figure formed by two rays called sides having a common endpoint called the vertex |
| associative property of addition | changing the groupings of three or more addends does not change the sum |
| chord | a line segment whose endpoints lie on a circle a diameter is a chord that passes through the center of the circle |
| Associative Property of Multiplication | Changing the groupings of three or more factors does not change the product. |
| circumference | the distance around a circle |
| coordinate plane | a grid formed by two axes that intersect at the origin The axes divide the coordinate plane into four quadrants. origin--intersection of the horizontal and vertical axes in the coordinate plane described by the ordered pair (0, 0) |
| denominator | the number of same-size parts in a whole or set |
| diameter | a chord that passes through the center of a circle |
| elapsed time | the amount of time that passes between two points in time |
| equally likely | two events with the same probability of occurrence |
| expression | an mathematical phrase that represents a quantity; may contain variables, numbers, and/or operations |
| coordinate plane | a grid formed by two axes that intersect at the origin The axes divide the coordinate plane into four quadrants. origin--intersection of the horizontal and vertical axes in the coordinate plane described by the ordered pair (0, 0) |
| denominator | the number of same-size parts in a whole or set |
| factor | a number that is multiplied by another number to find a product |
| frequency | the number of times an outcome occurs |
| line plot | A line plot shows the spread of data and each piece of data is represented by an x |
| greatest common factor | the largest number that divides evenly into two or more numbers |
| intersecting lines | lines that meet or cross in exactly one point |
| kite | a quadrilateral with two pairs of adjacent sides congruent but not four congruent sides |
| least common denominator | least common multiple of two or more denominators |
| least common multiple | the smallest multiple that each of two or more numbers share |
| least common multiple | the smallest multiple that each of two or more numbers share |
| likelihood (of an event) | the chance or probability that an event occurs |
| line graph | a graph using line segments to connect the graphed data points |
| mean | a measure of central tendency; the arithmetic average; a mathematical representation of the typical value of a series of numbers, computed as the sum of all the numbers in the series divided by the count of all numbers in the series. |
| median | a measure of central tendency; in a set of ordered data, the middle valueIf the data are shown with a histogram the "mode" is simply the value which corresponds to the highest point(s) on the curve. |
| least common multiple | the smallest multiple that each of two or more numbers share |
| likelihood (of an event) | the chance or probability that an event occurs |
| metric measurement system | a system of measurement based on multiples of 10; basic units are meter (length), gram (mass), and liter (volume or capacity) |
| mode | a measure of central tendency; the value(s) that occurs most often |
| numerator | a representation of the number of same-size parts being considered in terms of the |
| ordered pair | Identifies a location in a coordinate plane |
| parallel lines | coplanar lines that do not intersect |
| parallelogram | a quadrilateral with both pairs of opposite sides parallel |
| perpendicular lines | lines that intersect to form right angles |
| place value | the value a digit represents depending on its place in the number(tenth, hundredth, thousandth) |
| plane | described as a flat surface that extends infinitely in all directions; has two dimensions |
| polygon | a two-dimensional, simple, closed geometric figure that has line segments as sides |
| quadrant | one of four portions into which a plane is divided by the horizontal and vertical axes |
| radius | a line segment from the center of a circle to any point on the circle |
| range (of a set of data) | a measure of variation; the difference between the greatest and least values in a data set |
| rational number | any number that can be written as a ratio (fraction, decimal) |
| rhombus | a parallelogram with all sides congruent |
| trapezoid | a quadrilateral with exactly one pair of parallel sides |
| tree diagram | a organized list of all possible outcomes for an event |
| triangle | a polygon with three sidesTriangles can be classified by their angle types. An acute triangle has 3 acute angles. A right triangle has exactly one right angle. An obtuse triangle has exactly one obtuse angle. |
| U. S. Customary measurement system | the system of measurement commonly used in the United States; common units are inches, feet, yards, and miles-length; ounces, pounds, and tons-weight; ounces, cups, pints, quarts, and gallons-capacity |
| variable | a symbol that represents an unknown quantity |
