How many degrees are in a triangle?

• A. 90°
• B. 180°
• C. 360°
• D. 270°

Answer: (B)

In any triangle, the sum of the interior angles is always 180 degrees. This fundamental property is true for all triangles, regardless of their type (acute, obtuse, or right). Therefore, if you take any triangle, for example, one with angles measuring 60°, 60°, and 60°, and add these angles together, you will see that they total 180 degrees. This consistent measurement reinforces the idea that any triangle cannot exceed this sum. The other options present values that represent sums of angles in different contexts: for instance, a full circle encompasses 360 degrees, which is far more than what is possible within the confines of a triangle.
