En el triángulo de posición siempre se cumple que:In the spherical navigational triangle (triángulo de posición), it always holds that:

Show the answer

Correct answer: c) Both the sides and the angles are, individually, less than 180°.

Why it is correct

The navigational triangle is a proper (Euler) spherical triangle formed by great-circle arcs, so every individual side and every individual interior angle is strictly less than 180°.

Why the others are not

  • a) In a spherical triangle the sum of the three sides lies between 0° and 360°, not a fixed 180°.
  • b) In a spherical triangle the sum of the interior angles is always greater than 180° (and less than 540°).
  • d) Option c) is a fundamental property of every Euler spherical triangle.

How to work it out in the exam

  1. Spherical navigational triangle: each side and each angle is individually less than 180°.
