- Here are some key points about triangles with parallel lines1:
- If a line intersecting two sides of a triangle is parallel to the remaining side, then the smaller triangle created by the parallel line is similar to the larger, original triangle.
- The side splitter theorem tells us that if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides those sides proportionally.

www.nagwa.com/en/explainers/578176108746/The intercept theorem can be used to prove that a certain construction yields parallel line (segment)s. If the midpoints of two triangle sides are connected then the resulting line segment is parallel to the third triangle side (Midpoint theorem of triangles).en.wikipedia.org/wiki/Intercept_theorem Lesson Explainer: Parallel Lines in a Triangle - Nagwa
