Global Triangle
Take the Earth and imagine drawing a line of latitude around the equator. Then drawing a line of longtitude all the way around the Earth such that it passes through the Prime Meridian. Next, imagine standing on the point of intersection of those 2 lines and then moving east from that point along the equator before drawing another line of longtitude from that new point.
These three lines have inscribed a triangle on the Earth. What is the sum of all the interior angles of that triangle in degrees?

It enscribes a triangle where every angle is a right angle! So we have 3 × 9 0 ∘ = 2 7 0 ∘
