Is it true that do the angles of a triangle always equal 180 based on the following text?

In several geometries, a triangle has three vertices and three sides, where three angles of a triangle are formed at each vertex by a pair of adjacent sides. In a Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180 , radians, two right angles, or a half-turn.
