Detailed explanation-1: -An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).
Detailed explanation-2: -A triangle is a basic polygon with three sides and three vertices. Since it has three sides, it has three interior angles. An angle that measures between 0° and 90° is called an acute angle. An acute triangle is a type of triangle in which all the three internal angles of the triangle are acute.
Detailed explanation-3: -A triangle that has three acute angels is called an acute triangle. A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle.
Detailed explanation-4: -If all the internal angles of a triangle are less than 90 degrees, then it is called an acute angle triangle. In the above figure, we can see, the three angles of the triangle are 69°, 85° and 26°.
Detailed explanation-5: -An acute triangle has three acute angles (utmost). An obtuse (or right) triangle has two acute angles. A triangle has at least two acute angles.
