# Calculate area of a triangle, taking into account the earth curvature watch

1. Calculate area of a triangle, taking into account the earth curvature

Hello everyone,

I'm trying to work out the area of a 2D triangle from where I stand on earth to a plane in the sky. I can do this however I'm trying to take into account the earths curvature.. And then add that to the total area of the triangle.

I already know the distance from me to the plane and also the height of the plane.

Is there a formula for this?

Thanks all
2. If you are an undergrad and have taken some topology maybe consider the surface area (between the three points) on a topological space with positive curvature.
