all the points. also they should always add up to 180. as if you think about it a triangle is half a square/rectangle.
The internal angles of any triangle add up to 180 degrees.
in a regular (equilateral) triangle, all angles are 60 degrees, to add up to 180
The sides don't add up to anything but the angles should add up to 180 degree to form right triangle or any other triangle.
All interior angles in any triangle add up to 180 degrees. A scalene triangle will have 3 different interior angles that add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees and the 3 exterior angles add up to 360 degrees
