| Additive Method | A solid modeling design method where geometric primitives are combined to create a single object. |
| Analyze | To examine methodically by separating into parts and studying their interrelations. |
| box-and-whisker plot | A graphic way to display the median, quartiles, and extremes of a data set on a number line to show the distribution of data. |
| Computer-Aided Design | A process that uses a computer to assist in designing something, such as a part, circuit, or building. |
| Coordinate Plane | A two-dimensional space formed by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis. |
| Design Statement | A statement that briefly describes the design goals and needs of stakeholders. |
| Geometric Primitive | The simplest two-dimensional or three-dimensional geometric shape. |
| Line Segment | A part of a line that extends between two points on that line. |
| Lower-Quartile Median | The median of the lower half of a data set. |
| Mathematical Model | A method of representing a real-world situation using mathematical concepts in order to understand and predict future behavior. |
| Mean | The sum of the terms in a data set divided by the number of terms in the data set. |
| Median | The middle number in a data set when the numbers are arranged in value order. |
| Model | An accurate representation of an object or phenomenon. Models can be visual, physical, mathematical, or computational and are often used in the development of scientific theories or the engineering of artifacts. |
| Ordered Pair | A pair of numbers that define the location of a point on the plane. The first number in the ordered pair is the x coordinate, and the second number is the y coordinate. |
| Perpendicular Lines | Lines that meet at a 90-degree angle. |
| Polygon | A closed geometric figure in a plane formed by connecting line segments endpoint to endpoint, with each segment intersecting exactly two others. Polygons are classified by the number of sides they have, so a triangle has three sides, a quadrilateral has four sides, and a pentagon has five sides. |
| Problem Statement | A clear and concise identification and description of the design problem or opportunity. |
| Section View | A view of an object’s internal features and dimensions that allows designers to inspect the inside of solid models. |
| Solid Modeling | The process of creating a solid model or 3D object using a modeling and design application on a computer. |
| Subtractive Method | A solid modeling design method where parts of a whole geometric primitive are removed to create a new object. |
| Three-Dimensional | Having the dimensions of height, width, and depth. |
| Tree Diagram | A mathematical model used to help identify all possible outcomes in a real world situation. |
| Two-Dimensional | Having the dimensions of length and width. |
| Upper-Quartile Median | The median of the upper half of a data set. |
| Vertices | Plural of vertex. A vertex is the point where two or more sides (or edges) of a shape meet. |
