The segment that If a line is parallel to one side of a triangle and intersects the other two sides, then it divides the sides into segments of proportional lengths. 5 rating. 1789-g \(www. Learning Target 2: To be able to use proportional parts with parallel lines. 5 Worksheet Mon. If a line is parallel to one side of a triangle and intersects the other two sides in two distinct points, then it separates these sides into segments; Triangle Proportionality Converse: If a line intersects two sides of a triangle and separates the sides into corresponding segments of proportional lengths Parallel Lines and Proportional Parts 1. +8 2x-5 22.
