I miss my home way too much because my university is so far away from it. There are three places around my home that I really love. I used to visit them a lot, and each of them holds many memories for me. The three locations are listed below in order. (download it)

Place a point exactly on the Google Maps pin of each location. Use the three pinned locations as points A, B, and C. Connect points A, B, and C to form triangle ABC. Assume that triangle ABC is isosceles at A, meaning: AB = AC

Draw the altitude AH from point A to side BC. Since triangle ABC is isosceles at A, AH is also the median of BC. Therefore, H is the midpoint of BC, which means: BH = HC

The coordinate of point H is the flag.

FLAG FORMAT: LYKN{latitude,longitude} The coordinates must be taken from Google Maps. Round both latitude and longitude to 3 decimal places. Do not include any spaces inside the flag. Example: LYKNCTF{125.231,35.256}
