  1. 3. Angle - An angle formed by one side of a polygon and the extension of an adjacent side.
  2. 5. Angles - Two nonadjacent angles formed by two intersecting lines
  3. 8. Pair - A pair of adjacent angles whose non-common sides are opposite rays.
  4. 11. - If 2 pairs of corresponding sides and the included angle are congruent, then the 2 triangles are congruent . (Side-Angle-Side)
  5. 13. - A segment from a vertex to the midpoint of the opposite side
  6. 15. Interior Angles Theorem - The two remote interior angles within a triangle that are added together are equal to the exterior angle.
Down
  1. 1. - A perpendicular segment from a vertex to the line containing the opposite side.
  2. 2. Pair Theorem - If two angles form a linear pair, then they are supplementary.
  3. 4. of Concurrency - Point where three or more lines intersect.
  4. 6. Triangle - Triangle with at least 2 sides congruent.
  5. 7. Interior Angles - Interior angles that are not adjacent to the exterior angle.
  6. 9. - If 2 pairs of corresponding angles and the non-included side are congruent, then the 2 triangles are congruent . (Angle-Angle-Side)
  7. 10. - If all 3 pairs of corresponding sides are congruent, then the 2 triangles are congruent . (Side-Side-Side)
  8. 12. - If 2 pairs of corresponding angles and the included side are congruent, then the 2 triangles are congruent . (Angle-Side-Angle)
  9. 14. Angle - An angle inside a polygon.
