| Question | Answer |
|---|---|
| Polygon | A closed figure made up of line segments |
| Vertex | The point where two or more sides meet |
| Interior angle | Angle formed on the inside of a polygon by two sides meeting at a vertex |
| Exterior angle | Angle formed on the outside of a geometric shape by extending one of the sides past a vertex |
| Supplementary angles | Angles that add up to 180 degrees |
| Complementary angles | Angles that add up to 90 degrees |
| Polygon exterior angle sum theorem | The sum of the exterior angles in a triangle is 180 degrees |
| Exterior angle theorem | The exterior angle at each vertex of a triangle is equal to the sum of the interior angles at the other two verticies |
| Angle sum triangle theorem | The sum of the interior angles of a triangle are 180 degrees |
| Adjacent | Adjoining or next to |
| Transversal | A line intersecting two parallel lines |
| Obtuse angle | Angle greater than 90 degrees |
| Acute angle | Angle less than 90 degrees |
| Convex polygon | A polygon where all interior angles are less than 180 degrees |
