Geometry problem

  1. Oct 29, 2013 #1
    In the figure attached, I have to prove AB=2CE given that: line AC is parallel to DE and angles as mentioned in the figure. Can anyone please help me to prove the same?

    Calculate angles of the triangle ##CDE## in terms of ##\angle BAC## Then use the sine formula to relate ##|CE|## to ##|CD|##

    ∠BAC can vary and so will the angles of the Triangle CDE

    They can. But they're related, so you can express one in terms of the other.
