A scalene triangle is defined as one with all 3 sides having different lengths or all 3 angles being different. These two definitions are the same.

A scalene triangle is one whose sides are unequal - each side is different in length.
If you are only given the side lengths of a scalene triangle, it is impossible for you to find for the area, unless you are given more information... like the height of the triangle for example. If this is a right triangle you would like to find the area of, you can multiply the length of each leg with each other, and then divide that product by 2 to conclude the area of the triangle.
A Triangle has THREE sides. ; not necessarily equal . However, triangles are then sub-divided into ;- EQUILATERAL ; All three sides are the same length , and all three angles are 60 degrees. ISOSCELES ; Two sides are of equal length and two angles are of equal size. RIGHT-ANGLED ; All three sides can be of different length , or it can be an Isosceles triangles. However, there MUST be ONE RIGHT Angle (90 degrees). SCALENE ; All three sides are of different length , and all three angles are of different size.
It's can be any number ,but it has to equal up to 180 degrees
1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides
