Prove it

Let ABCABC be a triangle with AC>BCAC>BC. Let DD be the midpoint of the arc ABAB that contains CC, on the circumcircle of ABC\bigtriangleup ABC. Let EE be the foot of the perpendicular from DD on ACAC. Prove that AE=EC+CBAE = EC + CB.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Comments

It is the Archimedes Broken Chord Theorem, the solution directly follows.
Here is my proof for the following theorem. Note : - It is a proof for the theorem so, I have proved that ADAD = BCBC + DCDC. Using this theorem you can get your desired result. As in the setup given in Prove It is DD is the midpoint of the arc ACBACB and also, DEACDE \perp AC .Therefore AE=EC+CBAE = EC + CB....
