The 3 interior angles in any triangle always add up to 180 degrees. This is true for Euclidean geometry (i.e. geometry on a flat surface) which is what most people will always deal with. Non-Euclidean geometry is concerned with geometry that isn't on a flat plane such as the globe and is used mostly in advanced physics and mathematics such as in the general theory of relativity.

What angle do triangles always add up to?
180 degrees.
How many degrees does a scalene triangle have?
All triangles add up to 180 degrees including scalene.
Parts of the triangle?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees Triangles are classed as scalene, right angle, obtuse, isosceles and equilateral
How many triangles exist with the given angle measures 30 65 85?
As many as you like but they will all be scalene triangles formed by the given angles that add up to 180 degrees
What does equilateral triangle look like?
Three sides of equal length and thus all angles are each 60 degrees, because all triangles add up to 180 degrees
