6.1 terms

  1. 1. Terms of EndearmentPolygons: 6.1
  2. 2. Polygon• Plane figure with the following conditions: • Formed by 3 or more segments (sides), such that no two sides with common endpoints are collinear • Each side intersects exactly two other sides, one at each point
  3. 3. Vertex of a Polygon• Each endpoint of a side (the point of intersection for each side of a polygon)
  4. 4. Convex Polygon• No line containing a side of the polygon contains a point on the interior of the polygon• Basically, if you were to extend a side in both directions (forming the line mentioned above), the extension of the side would not go through the inside of the polygon
  5. 5. Concave Polygon• The extension of a side of a polygon does go through the interior of the polygon
  6. 6. Equilateral Polygon• A polygon with all of its sides congruent
  7. 7. Equiangular Polygon• A polygon with all of its interior angles congruent
  8. 8. Regular Polygon•A polygon is “regular” if it is equilateraland equiangular
  9. 9. Diagonal of a Polygon•Segment that joins two non-consecutivevertices•Basically, a diagonal connects two cornersthat don’t connect to form one of the sides•A rectangle would have two diagonals(forming an X) on its interior
  10. 10. Interior Angles of a Quadrilateral• This Theorem says that the sum of the interior angles in a quadrilateral (4-sided figure) is 360• To justify this, a rectangle can be split to form two triangles…each triangle has a sum of 180 degrees… so 180 + 180 = 360
