Across
  1. 5. if two sides of one triangle are congruent to two sides of another triangle, the triangle with the larger included angle has the longer third side
  2. 8. the point where the perpendicular bisectors of the side of a triangle intersect
  3. 10. intersect to form a right angle
  4. 12. never intersect
  5. 13. special points formed by the intersection of specific lines within a triangle
  6. 15. the point where the three medians of a triangle intersect
  7. 16. the sum of the lengths of any two sides of a triangle must be greater than the length of the third side
  8. 17. middle point of a line segment
Down
  1. 1. the point of concurrency where the three angle bisectors of a triangle intersect
  2. 2. a line segment that extends from a vertex of the triangle perpendicular to the opposite side
  3. 3. the measure of any exterior angle of a triangle is greater than the measure of either of its two nonadjacent interior angles
  4. 4. the point where its three altitudes intersect
  5. 6. a ray that divides an angle into two congruent adjacent angles
  6. 7. line, ray, or segment that intersects another segment at its midpoint, forming a 90 degree angle
  7. 9. length between two points
  8. 11. line segment that connects a vertex to the midpoint of the opposite side
  9. 14. polygon with three edges and three vertices
