| Complementary Angles | When the sum of 2 angles = 90°, they are called complementary angles |
| Supplementary Angles | When the sum of 2 angles = 180°, they are called supplementary angles |
| Units for Angles | Degrees, radians |
| Area | Measurement of the amount of surface of an object |
| Sector | The plane figure enclosed by two radii of a circle and the arc between them. |
| Polygon | A polygon is an enclosed shape made up of straight lines. |
| Regular Polygon | A regular polygon has all its sides and angles equal. |
| Apothem | The line joining the center of a regular polygon to the mid point of any of its sides |
| Volume | The amount of space contained within a solid |
| Cube | Cube is a special type of rectangular solid |
| Cylinder | Solid having the shape of a can, or length of a pipe, or a barrel |
| Piston Displacement | Total volume (in cubic inches, cubic centimeters, or liters) swept by all of the pistons of a reciprocating engine as they move in one revolution of the crankshaft |
