scalene triangle
a triangle with no congruent sides
A scalene triangle is a type of triangle that has three sides of different lengths. In other words, none of the sides of a scalene triangle are equal in length. Additionally, the angles of a scalene triangle are also of different measures.
Properties of a Scalene Triangle:
1. All three sides have different lengths.
2. All three angles have different measures.
3. The perimeter is the sum of the length of all three sides.
4. The area can be calculated using Heron’s formula.
Heron’s Formula:
Heron’s formula is a formula used to calculate the area of any triangle, including the scalene triangle. It is given as follows:
Area of a scalene triangle = √s(s-a)(s-b)(s-c)
where ‘a’, ‘b’ and ‘c’ are the lengths of the sides and ‘s’ is the semiperimeter (half of the perimeter) of the triangle.
In summary, a scalene triangle is a type of triangle with three unequal sides and angles. It has unique properties and can be identified using its characteristics. Additionally, the area of a scalene triangle can be calculated using Heron’s formula.
