Across
- 3. either of the two sides that are not directly between the two angles being used
- 7. a polygon with three edges and three vertices
- 9. two right triangles are congruent if the hypotenuse and one leg of one right triangle are congruent to the other right triangle's hypotenuse and leg side
- 13. statement says that two polygons are congruent
- 14. two triangles that have corresponding sides of the same size
- 16. a line segment that joins two vertices in a shape
Down
- 1. if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.
- 2. the longest side of a right-angled triangle
- 4. triangle a triangle with a right angle
- 5. if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
- 6. the figure formed by two rays
- 8. the two sides that intersect to determine the right angle
- 10. if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
