 World's Hardest Easy Geometry Problem 1
 此主题相关图片如下：
Using only elementary geometry, determine angle a.
You may only use elementary geometry, such as the fact that the angles of a triangle add up to 180 degrees and the basic congruent triangle rules (side-angle-side, etc.). You may not use more advanced trigonomery, such as the law of sines, the law of cosines, etc.
This is the hardest problem I have ever seen that is, in a sense, easy. It really can be done using only elementary geometry. This is not a trick question.
Sorry, but I'm not giving the answer here. You will just have to work on it until you either solve it or are driven insane.
