Scalene triangle

A scalene triangle is a type of triangle that has three unequal side lengths

A scalene triangle is a type of triangle that has three unequal side lengths. In other words, all three sides of a scalene triangle have different lengths. Additionally, all three angles of a scalene triangle are also different from each other. This is in contrast to an equilateral triangle, where all three sides and angles are equal, or an isosceles triangle, where two sides and two angles are equal.

One important property of a scalene triangle is that the longest side is always opposite the largest angle. This is known as the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Another interesting fact about scalene triangles is that they do not have any lines of symmetry. This means that if you were to fold a scalene triangle along any axis, the two halves would not be identical.

To determine the area of a scalene triangle, you can use the formula:

Area = (1/2) * base * height

where the base is the length of one side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. It is important to note that the height must be measured from the base to the opposite vertex, not just any point inside the triangle.

You can also find the angles of a scalene triangle using various trigonometric functions. For example, the Law of Sines can be used to find the measures of angles if you know the lengths of two sides and the measure of the angle opposite one of those sides. The Law of Cosines can be used to find the lengths of sides and the measures of angles if you know the lengths of all three sides.
