Final answer:
A line intersects two sides of a triangle and forms a similar triangle sometimes.
Step-by-step explanation:
When a line intersects two sides of a triangle, it forms a triangle that is sometimes similar to the given triangle. Whether or not the formed triangle is similar depends on the angles created at the points of intersection. If the angles formed are equal in both triangles, then they are similar. However, if the angles formed are not equal, the triangles are not similar. Similar triangles have corresponding angles that are equal and corresponding sides that are proportional.
