Across
  1. 1. A line segment connecting a vertex of a triangle to the midpoint of the opposite side. It divides the triangle into two triangles of equal area.
  2. 6. A point where three or more lines coincide.
  3. 8. A circle inside a triangle that is tangent to all three sides.
  4. 9. A line, ray, or line segment that divides an angle into two equal angles. In a triangle, an angle bisector extends from a vertex to the opposite side.
  5. 10. The point of concurrency of all the side perpendicular bisectors of a triangle.
Down
  1. 2. An additional line or line segment drawn in a geometric figure to help solve a problem or prove a statement.
  2. 3. The point of concurrency of all the altitudes of a triangle.
  3. 4. The point of concurrency of all the angle bisectors of a triangle.
  4. 5. A segment that joins the midpoints of two sides of a triangle or a trapezoid.
  5. 7. A circle that passes through all three vertices of a triangle.
  6. 10. The point of concurrency of all the median of a triangle.
