Any triangle, and all triangles.
In a triangle, if an angle is adjacent (shares a side) and supplementary (adds up to 180 degrees) to one of the interior angles, it means that the two angles together form a straight line. In other words, the three angles of the triangle add up to 180 degrees.
All the angles of a triangle add up to 180 degrees. In a right triangle one of the angles must be 90 degrees and the other two can be any combination that adds to 90, such as 30 degrees and 60 degrees.
they add up to 180 degrees
Because the total sum of angles in any triangle adds up to 180 degrees.
A set of angles can form a triangle if the sum of the three angles is exactly 180 degrees. Additionally, each angle must be greater than 0 degrees. This means that any combination of three positive angles that adds up to 180 degrees qualifies as the angles of a triangle. For example, angles of 60°, 60°, and 60° or 30°, 60°, and 90° both form valid triangles.
It doesn't matter what type of triangle it is, or the length of the sides. The sum of the interior angles of a triangle always adds up to 180 degrees

The three angles included in the triangle adds up to 180 degrees.

They don't. The interior angles of a triangle add up to 180°. The complements of each of these angles adds up to 360°. So 3 times 360 minus 180 = 900. This is your answer.

All the angles of a triangle add up to 180 degrees. In a right triangle one of the angles must be 90 degrees and the other two can be any combination that adds to 90, such as 30 degrees and 60 degrees.
The sum of all the angles in a triangle always adds up to 180 degrees.
If you add up the degrees of all the angles in a triangle, it adds up to exactly 180 degrees every time.
they add up to 180 degrees
The interior angles of an 8 sided octagon add up to 1080 degrees
Because the total sum of angles in any triangle adds up to 180 degrees.
