| Question | Answer |
|---|---|
| Degree | A unit of measure: 360 of them make a full circle. |
| Radian | A unit of measure: 2 pi of them make a full circle. |
| Exterior Angle | An angle outside a polygon formed by two adjacent sides of the polygon. |
| Interior Angle | An angle inside a polygon formed by two adjacent sides of the polygon. |
| Exterior Angle | The Supplement of an Interior Angle. |
| Interior Angle | The Supplement of an Exterior Angle. |
| Line of Symmetry | A line about which a shape can be folded in half so that both halves overlap with one another. |
| Line of Symmetry | If you put a mirror along this line, you can see the whole shape. |
| Perpendicular Lines | Two lines that intersect in a right angle. |
| Parallel Lines | Two lines that never intersect. |
| Transversal | A line that intersects two or more lines. |
