WebIn geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet. They can be both horizontal and vertical. We can see parallel lines examples in our … WebNov 28, 2024 · 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 transversals. WebStudents will be able to. recognize when parallel lines inside or outside triangles create similar triangles (sometimes called the side splitter theorem), use proportionality to find unknown lengths in triangles containing parallel lines, solve multistep problems involving triangles containing parallel lines, prove that a straight line is ... interruptio bfs.admin.ch
