| angle of depression | The angle between the line of sight and the horizontal when an observer looks downward |
| area | The number of square units that covers a shape or figure. |
| balance | Having the same weight (mass) on either side |
| central angle | An angle that has its vertex at the center of a circle. |
| circle graph | A way to display data by using a circle dividing into non-overlapping sectors |
| complimentary angles | Two angles whose sum is 90 degrees. |
| composite figure | A plane figure made up of triangles, rectangles, trapezoids, circles, and other simple shapes, or a three-dimensional figure made up of prisms, cones, pyramids, cylinders, and other simple three-dimensional figures. |
| congruent | Figures or angles that have the same size and shape. |
| constant | A value that does not change. |
| coordinate plane | The plane determined by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis, intersecting at a point called the origin. Each point in the coordinate plane can be specified by an ordered pair of numbers. |
| diagonal | The line segment connecting two nonadjacent vertices in a polygon. |
| diameter | The line segment joining two points on a circle and passing through the center of the circle. |
| edges | Where two surfaces join (intersect) |
| faces | A flat surface of a three-dimensional figure. |
| fractal | A figure generated by repeating a special sequence of steps infinitely often. Fractals often exhibit self-similarity. |
| frequency table | A data listing which also lists the frequencies of the data. |
| function | A relation in which every input is paired with exactly one output. |
