State the rule which connects BT, EA, and BA.
this is a topic of plane geometry and we were given a directed investigation 'How far can you see the horizon?' this is it....the circle represents a cross-section of the Earth. imagine you are in a balloon at B. BT shows the furthest point, T, on the Earth's surface that you could see. imagine that you have just dropped a very heavy, sharp object from your balloon. the object, hits the ground at E, directly below you, boring its way through Earth coming to a stop just as it reaches the antipodal point A.
