Across
- 6. If two angles and a nonincluded side of one triangle are congruent to the corresponding angles and nonincluded side of another triangle, then the triangles are congruent.
- 7. if two lines are intersected by a transversal, and the alternate exterior angles formed are congruent (equal), then the two lines must be parallel
- 8. Given two lines cut by a transversal, if alternate interior angles are congruent, then the lines are parallel.
- 9. If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
- 10. In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides
Down
- 1. Given a point and a line not containing it, there is exactly one line through the given point perpendicular to the given line.
- 2. If all three corresponding sides of two triangles are equal, the triangles are congruent.
- 3. If two angles and a nonincluded side of one triangle are congruent to the corresponding angles and nonincluded side of another triangle, then the triangles are congruent.
- 4. If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
- 5. once two triangles are proven to be congruent, then the three pairs of sides that correspond must be congruent and the three pairs of angles that correspond must be congruent.
