In Euclidean Geometry: If it is a triangle with 3 sides yes it does. In Reimannian Geometry: No, they actually add up to more than 180 degrees. Let's use the Earth. Longitudinal Lines intersect the Equator at 90 degree angles, and originate from the North Pole. Pick any two longitudinal lines, extend them from the North Pole to the Equator, and presto! A triangle with more than 180 degrees.

How many triangles does a 10 sided shape have?
8 because there are 180 degrees in a triangle and 8*180 = 1440 degrees The interior angles of a 10 sided shape add up to 1440 degrees

Use geometry words to describe how diagonals of quadrilaterals make triangles?
All triangles have 3 interior angles that add up to 180 degrees and the 4 interior angles of a quadrilateral add up to 360 degrees but if 2 of its vertices are joined by a diagonal this marks out 2 interior triangles each having 3 interior angles adding to 180 degrees.
