You have a Triangle ABC. You have three lines drawn from vertex A to segment BC... AX is an altitude. AY is an angle bisector. AZ is a median. Segments AX, AY, and AZ quadrasect Angle BAC.

Your task: Prove that Triangle ABC is a right triangle.

I think this is kinda tough, so good luck.

From what I've read we know that the sun gives us energy but for the sun to give us continious energy it has to be given energy as well. Some scientist even say they donot know the answer to this question, is it true? If there is some source greater than you and I out there than what is it? I believe no-one has even been where the sun is.
