Question

What do the sides in a triangle add up to? I know that the inner angles of a triangle add up to 180°, but what do the sides of a triangle add up to?

Answer 1

The most basic fact about triangles is that all the angles add up to a total of 180 degrees. The angle between the sides can be anything from greater than 0 to less than 180 degrees. The angles can't be 0 or 180 degrees, because the triangles would become straight lines.
