  1. 2. Point of concurrency for the 3 altitudes of a triangle.
  2. 4. If you connect any 2 points of a polygon, at least one of the segment (diagonals) formed will be outside the polygon.
  3. 5. a quadrilateral that has opposite sides that are parallel, and their opposite sides and angles are equal.
  4. 9. A quadrilateral that has exactly two sides that are parallel.
  5. 10. A theorem that states that in a right triangle, the sum of the squares of the legs will always equal the square of the hypotenuse: a²+b² = c²
  6. 12. The point of concurrency of the angle bisectors of a triangle.
  7. 15. The ratio of the lengths of two corresponding sides of similar figures. Image over preimage
  8. 17. A transformation that is a reduction or an enlargement of a shape.
  9. 18. a polygon in which all sides and the angles are congruent.
  10. 19. If you choose any two points inside the polygon, the line segment (diagonal) that connects them will be inside the polygon.
Down
  1. 1. A triangle in which at least two sides have the same length.
  2. 3. A triangle that has three equal sides, each of the angles measures 60°
  3. 4. Point of concurrency of the 3 perpendicular bisectors of a triangle. It is equidistant from all three vertices.
  4. 6. Point of concurrency of the 3 medians of a triangle. Is the balancing point.
  5. 7. A figure formed by three or more segments called sides. Each side intersects exactly two other sides at their endpoints.

  7. 11. A quadrilateral with two pairs of consecutive congruent sides and no opposite sides congruent.
  8. 13. a parallelogram with four right angles
