No matter how you position the three sides of the triangle, the total degrees of all interior angles (the three angles inside the triangle) is always 180°. Vertical angles are opposite angles in such an intersection. Relations between Angles and Sides in Triangles. If you know what all the forces sum up to, then you can use some pictorial vector math and determine the unknown angle $\theta$ in terms of $\phi$ without doing math. Let's draw a line segment from point P down to (and perpendicular with) the horizontal radius. An example of this relationship would be angles 1 and 8, as well as angles 4 and 5.
