Across
- 2. / line that intersects two or more coplanar lines at distinct points
- 6. / if a triangle is equilateral, then the triangle is equiangular
- 7. / nonadjacent exterior angles that lie on opposite sides of the traversal
- 12. / In a plane, if a line is perpendicular to one of two parallel lines, then it is also perpendicular to the other
Down
- 1. / if two angles of a triangle are congruent, then the sides opposite those angles are congruent
- 3. / if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent
- 4. / noncoplanar that are not parallel nor intersect
- 5. / if two angles of one triangle are congruent to two angles of another triangle then the third angles are congruent
- 8. / the ratio of the vertical change to the horizontal change between any two points
- 9. / the side opposite the right angle; the longest side in a right triangle
- 10. planes / planes that do not intersect
- 11. / planes that do not intersect
