The antipodal position of a place located at 35Рsouth and 80Рwest is :

An antipodal position refers to the point diametrically opposite to a specific location on Earth. To calculate it, two rules are applied: first, the latitude remains the same numerical value but shifts to the opposite hemisphere [t1][t3]. Thus, 35° South becomes 35° North. Second, the longitude is calculated by subtracting the original value from 180° and reversing the direction (East to West or vice versa) [t3][t5]. For a location at 80° West, the calculation is 180° - 80° = 100°, and the direction changes to East [t1][t5]. Therefore, the antipode of 35° South and 80° West is 35° North and 100° East. This mathematical relationship ensures the two points are separated by 180° of longitude and equal but opposite latitudes, passing directly through the Earth's center [t4][t6].
