Final answer:
To prove CA/BA = DA/EA, use the property of similar triangles in triangle ACD with line BE parallel to line CD.
Step-by-step explanation:
To prove that CA/BA = DA/EA in triangle ACD with line BE parallel to line CD, we can use the property of similar triangles.
- Since line BE is parallel to line CD, we can determine that triangle ABC is similar to triangle ADE.
- By the property of similar triangles, the corresponding sides of the two triangles are proportional.
- Therefore, CA/BA = DA/EA.
