<P> Angles between adjacent sides of a triangle are referred to as interior angles in Euclidean and other geometries . Exterior angles can be also defined , and the Euclidean triangle postulate can be formulated as the exterior angle theorem . One can also consider the sum of all three exterior angles , that equals to 360 ° in the Euclidean case ( as for any convex polygon ) , is less than 360 ° in the spherical case , and is greater than 360 ° in the hyperbolic case . </P>
