Angle Relationships
Math Vocabulary
| Term | Definition |
|---|---|
| Adjacent Angle | two angles that have a common side and a common vertex (corner point), and don't overlap |
| Area | The size of a surface; The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle. |
| Circumference | The distance around the edge of a circle (or any curvy shape). It is a type of perimeter |
| Complementary Angle | two Angles that add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. |
| Composite Area | is found by adding together the areas of the individual figures. |
| Cross section | this is of a solid is a plane figure obtained by the intersection of that solid with a plane. This represents a "slice" of a solid, and may be different depending on the orientation or direction of the slicing plane. |
| Diameter | A straight line going through the center of a circle connecting two points on the circumference. |
| Formula for area of circle | A= πr2 |
| Formula for circumference of circle | c = 2πr or c = πd |
| Net | A pattern that you can cut and fold to make a model of a solid shape. |
| Pi | Pi: The ratio of a circle's circumference to its diameter; Equal to 3.14159265358979323846... (the digits go on forever without repeating); A rough approximation is 22/7 (=3.1428571...), but that is not very accurate |
| Plane | a flat, two-dimensional surface that extends infinitely far in all directions. |
