Theorem to prove parallel lines
Webb18 juli 2012 · The Triangle Proportionality Theorem states that if a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally. We can extend this theorem to a situation outside of triangles where we have multiple parallel lines cut by transverals. Webb9 sep. 2024 · The theorems, definitions, that can be used to prove that alternate exterior angles are congruent are; 1) Corresponding angles postulate 2) Vertical angles theorem 3) Transitive property of congruency The explanation and reasons on how they are applied as proof are as follows: Question: Please find attached the diagram representing the question
