- 33. if two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent
- 34. if two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the two triangles are congruent
- 35. if two lines are parallel to the same line, then they are parallel to each other
Down
- 1. If two points lie in a plane, then the line containing them lies in the plane
