Thank you.

The triangle formed, especially in the geodetic survey, is nothing but the spheroidal triangle.

A geodetic survey is carried out when the distance is more than 250 km. The curvature of Earth is taken into consideration.

Thank You.

There’s no such thing as sheroid triangle. I think you wanted to type **spheroid triangle.**

Spheroid triangle is nothing but a triangle on a sphere (the Earth). In surveying, when three points on the Earth are taken which are at least about a few kilometers apart, the lines joining them will be **curves but not straight lines** because of the Earth’s curvature. The three curved figure made by these curves with each of our points as vertices is a spheroid triangle.

We denote this kind of a because triangle separately in this way because we cannot apply normal trigonometry to this triangle since the **sum of the angles is greater than 180º**. If we do that, we’ll end up with wrong calculations. So, adjustments first need to be done. They are already taken care of in GPS positioning.
