Question from Nazrul, a teacher: ABC is a triangle , D is the mid point of AB and DE is parallel to BC where E lies on AC. How can I prove that E is the mid point of AC. |
Nazrul,
DE is parallel to BC. What does that tell you about angles ADE and ABC? What does that tell you about triangle ADE and ABC?
