Across
  1. 1. ray that passes through a midpoint of another segment.
  2. 4. when two triangles with two pairs of equal corresponding angles are similar.
  3. 9. a line perpendicular to the side and passing through its midpoint.
  4. 12. a segment that connects the midpoints of two sides of a triangle
  5. 13. figures that are the same shape, but not necessarily the same size.
  6. 16. line segment that divides the angle into two equal parts
  7. 18. created by the intersection of the three angle bisectors of each triangle
  8. 19. have the same or a constant ratio
  9. 20. created by the intersection of the three perpendicular bisectors of each side.
Down
  1. 2. same shape and size.
  2. 3. an angle inside a polygon at a vertex of the polygon.
  3. 5. created by the intersection of the three altitudes in the triangle.
  4. 6. equally distant.
  5. 7. created by the intersection of the three medians in the triangle
  6. 8. if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.
  7. 10. the line which is perpendicular to a given line segment and which divides it into two equal line segments.
  8. 11. a line segment drawn from any vertex of a triangle to the midpoint of the opposite side.
  9. 14. when a circle is tangent to the three sides of a triangle.
  10. 15. corresponding sides are equal in length, and their corresponding angles are equal in measure.
  11. 17. a line segment drawn from any vertex of a triangle perpendicular to the opposite side
