Which country is the owner of Dokdo?
<One of the reasons why you cannot resist the fact that Dokdo is an island of KOREA>
Dokdo is definitely a land of Korea's. However, Japan is claiming that Dokdo is their land and one of the reasons is that ‘you cannot even see Dokdo from your own land, Korea.' Japan has said “You guys cannot see Dokdo from Ulleungdo(name of Korea's island)." To correct them and show them that we can actually see the island Dokdo, a photographer Ocheol Gwon attempted to take a picture of Dokdo from Ulleungdo. To get the perfect position and an altitude of the camera, he used Trigonometric ratio and Pythagorean theorem to do the math. After finding the exact angles, he was able to get a beautiful picture of Dokdo. In Ulleung Island in November 2014, the picture of our land Dokdo was able to confirm that Dokdo is our land, not Japan's.
