How many degrees are in a triangle?
Correct answer: A. 180
- A. 180
- B. 90
- C. 360
- D. 270
Explanation
A triangle is a three-sided polygon, and the sum of its interior angles is always 180 degrees. This is a fundamental property of triangles and applies to all types of triangles, including equilateral, isosceles, and scalene. Option A is correct because it correctly identifies this sum. Option B is incorrect as 90 degrees is the measure of a single right angle. Option C is incorrect because 360 degrees is the sum of the interior angles of a quadrilateral, not a triangle. Option D is incorrect as 270 degrees does not represent the sum of angles in any basic geometric shape.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
