What Is a Scalene Triangle?
A Scalene Triangle Is a Triangle That Has Three Unequal Sides, Such as Those Illustrated Above. See Also: Acute Triangle, Equilateral Triangle, Isosceles...
.
In this way, what is an example of a scalene triangle?
Scalene triangles are triangles with three sides of different lengths. For example, a triangle with side lengths of 2 cm, 3 cm, and 4 cm would be a scalene triangle.
Likewise, what is the best definition of a scalene triangle? A scalene triangle is a triangle with all the three unequal sides. None of its sides is equal to any other. But like other triangles, all the angles inside a scalene triangle add up to 180 degrees. Like if a triangle has sides 5 cm, 2 cm and 6 cm. Then it will be a scalene triangle.
In respect to this, what are the properties of scalene triangle?
Properties of the scalene triangle: All angles of a scalene triangle are unequal. A scalene triangle has no line of symmetry. The angle opposite to the longest side would be the greatest angle and vice versa. All sides of the given scalene triangle are unequal.
How do you identify a scalene triangle?
Identifying scalene triangles In addition to having three unequal sides, scalene triangles have three unequal angles. The shortest side is across from the smallest angle, the medium side is across from the medium angle, and — surprise, surprise — the longest side is across from the largest angle.
