Across
- 2. If two sides and the included angle are congruent to another triangle, the triangles are congruent.
- 4. Compares triangles that do not have all corresponding congruent parts; bigger side is opposite the bigger angle.
- 6. If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
- 10. When three or more lines, segments, or rays intersect at one common point.
- 13. A segment from a vertex that is perpendicular to the opposite side
- 14. The point of concurrency where the angle bisectors of a triangle intersect.
- 16. The point of concurrency where all three medians of a triangle intersect.
- 18. A triangle with all sides congruent and all angles measuring 60°: also is isosceles.
- 20. A line or line segment that intersects another line/line segment at a right angle(90 Degrees)and divides it into two equal parts at the other line/line segments midpoint.
Down
- 1. If two angles and the included side are congruent to another triangle, the triangles are congruent.
- 3. The point of concurrency where all three altitudes of a triangle intersect.
- 5. A segment connecting a vertex to the midpoint of the opposite side.
- 7. Two figures with corresponding congruent sides and corresponding congruent angles.
- 8. The point of concurrency where the perpendicular bisectors of the sides of a triangle intersect.
- 9. If two angles and a non-included side are congruent to another triangle, the triangles are congruent.
- 11. Congruent Parts of Congruent Triangles Are Congruent: A justification used after proving two triangles are congruent to conclude that their corresponding parts are also congruent.
- 12. A ray or segment that divides an angle into two congruent angles
- 15. In an isosceles triangle, the angle between the two congruent sides.
- 17. In an isosceles triangle, the side opposite the vertex angle.
- 19. A polygon with three sides and three angles.
