Regarding side length, a triangle is is an acute triangle if …
a² + b² > c²
A triangle is considered to be an acute triangle if all three angles of the triangle are acute angles, which means they are less than 90 degrees. An acute angle is an angle that measures greater than 0 degrees and less than 90 degrees.
Additionally, the side lengths of an acute triangle satisfy the following property: the square of the longest side is less than the sum of the squares of the other two sides. This property is also known as the Pythagorean Theorem.
For example, if we have a triangle with side lengths of 3, 4, and 5 units, we can determine if it is an acute triangle using the Pythagorean Theorem. The longest side is 5, and the sum of the squares of the other two sides is 3^2 + 4^2 = 9 + 16 = 25. Since 5^2 = 25, this triangle satisfies the Pythagorean Theorem and is an acute triangle.
