Interior angles of a triangle have a sum of 180 degrees.
Sum of angles in a triangle is 180
equilateral triangle (and so, if it is in Euclidean (plane) space, it has 3 angles all of which are 60°) otherwise (in Hyperbolic or Spherical space) it is an isosceles triangle.
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
All triangles have a total of 180 degrees for interior angles in Euclidean plane geometry
