What is the total number of degrees in a triangle?

In any triangle, the sum of all interior angles is always 180 degrees. This property holds true for all types of triangles, whether they are scalene, isosceles, or equilateral. The reasoning behind this can be understood through geometric principles, such as the fact that triangles can be derived from the angles formed by a straight line, where any angle on that line will always sum to 180 degrees.

Since a triangle is made up of three angles that combine to form a complete figure, it inherently reflects this principle of angle sum. Thus, the total number of degrees in a triangle is correctly defined as 180 degrees.
