There are several theorems to prove line relationships in plane geometry.
The proof of parallel lines is done by
- (3) Converse of Corresponding Angles Postulate
- (4) Converse of Same-Side Interior Angles Theorem
To prove that lines are parallel, we make use of the concept of line transversal.
The vertical angle theorem is based on two lines intersecting at a point
The alternate interior angle theorem is used to determine the congruence of angles in a transversal of parallel lines
The converse of corresponding angles postulate, and the converse of same-side interior angles theorem are used to determine if lines are parallel based on the angles on the transversal.
Hence, the true options are (3) and (4)
