Acute Triangle Definition

An acute triangle (or acute angled triangle) is a triangle in which all three interior angles are acute angles (less than π2 radians or 90 degrees). Acute triangles along with obtuse triangles are the two different types of oblique triangles (triangles that are not right triangles because they have no π2 radians or 90 degree angles).
