Across
  1. 5. Corresponding Parts of Congruent Triangles are Congruent
  2. 7. If two pairs of corresponding angles are congruent and the corresponding sides are congruent, then the triangles are congruent by this theorem.
  3. 8. If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.
  4. 9. A triangle with two congruent sides and two congruent angles.
  5. 12. If two sides of a triangle are congruent, then the angles opposite to those sides are congruent
  6. 16. The point of concurrency where the altitudes of a triangle intersect.
  7. 17. If all three pairs of corresponding sides are congruent, then the triangles are congruent by this theorem.
  8. 19. If two sides of one triangle are congruent to two sides of another triangle, and the included angles are not congruent, then the longer third side between the two triangles is opposite the larger included angles.
  9. 20. The point of concurrency where the angle bisectors of a triangle intersect.
Down
  1. 1. The intersection point of concurrent lines
  2. 2. If two pairs of corresponding angles are congruent and a pair of corresponding included sides are congruent, then the triangles are congruent by this theorem.
  3. 3. A polygon with three sides
  4. 4. Let a and b be two lengths of sides in a triangle, c is the third side, and a ≤ b. The length of c is in the range b-a <c<b+a
  5. 6. The point of concurrency where the perpendicular bisectors of a triangle intersect.
  6. 10. If the hypotenuse and leg of one right triangle are congruent to the other right triangle’s hypotenuse and leg, then the triangles are congruent by this theorem.
  7. 11. Three or more lines/segments/rays that intersect at a common point
  8. 13. If two pairs of corresponding sides are congruent and the corresponding included angles are congruent, then the triangles are congruent by this theorem.
  9. 14. The point of concurrency where the medians of a triangle intersect.
  10. 15. A line that intersects the vertex angle and is perpendicular to the opposite side
  11. 18. Two figures with corresponding congruent sides and corresponding congruent angles.
