Across
  1. 2. if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally.
  2. 3. the point formed by medians of a triangle is two-thirds of the distance from each vertex to the midpoint of the opposite side.
  3. 5. the circumcenter (formed by the perpendicular bisector) is equidistant from the vertices of the triangle.
  4. 7. if the three sides of one triangle are congruent to the corresponding sides to another triangle, then the two triangles are congruent.
  5. 8. the point where the perpendicular bisectors of the sides intersect.
  6. 10. segment joining a vertex to the midpoint of the opposite side of a triangle.
  7. 11. all corresponding sides and all corresponding angles are equal in measure.
  8. 12. if two sides and the included angle of one triangle are equal to two sides and the included angle of another corresponding triangle, the triangles are congruent.
  9. 15. if two angles and any side of one triangle are congruent to two angles and any side of another corresponding triangle, then the triangles are congruent.
  10. 16. the incenter is equidistant from the sides of the triangle.
Down
  1. 1. the location where three or more lines intersect.
  2. 4. if any two angles and their included side of one triangle are equal to any two angles and their included side of another corresponding triangle, then the triangles are congruent.
  3. 6. a segment that passes through the midpoint of a side of the triangle at a right angle.
  4. 9. is half of the length of the side parallel to it.
  5. 13. a line segment that goes from the vertex of a triangle to the opposite side and is perpendicular to it.
  6. 14. connects the midpoints of the sides of a triangle.
