Acute Triangle

An acute triangle is a triangle where all three interior angles are less than 90 degrees. This means the triangle's corners are sharp and pointed, and each angle is smaller than a right angle. Because all angles are acute, the sides tend to be relatively balanced in length, though they can vary. This type of triangle is common in many geometric shapes and designs, and its defining feature is that no angle is right or obtuse. Understanding this helps in recognizing and working with different triangle types in geometry and real-world applications.
