In general the 2 smaller sides of a triangle when added together must be greater than its biggest side.
A scalene triangle is a triangle in which there are no sides or angles with the same measures.

So?
A triangle with no equal sides and no equal angles is called a scalene triangle. In a scalene triangle, all three sides are of different lengths and all three angles are of different measures. This type of triangle does not have any symmetry and each side and angle is unique.
A triangle with three sides is a polygon.

A scalene triangle is a triangle in which there are no sides or angles with the same measures.
perimeter
Any and every triangle has three sides and three angles; that is the defintion. The type of triangle cannot be determined without more information.
A triangle by definition has three sides, so a shape with six sides cannot be a triangle. A shape with six sides would be classified as a hexagon. Triangles are specifically defined as polygons with three sides and three angles.
No it cannot. A triangle is by definition a three sided shape.
So?
A quadrilateral triangle is an oxymoron.A quadrilateral has four sides, a triangle has three so a quadrilateral triangle cannot exist. You could therefore say that it has zero sides.
you add up the measures of the sides Perimeter=a+b+cAdd up the three sides together
To find the perimeter of a triangle, add the three sides. Perimeter = 6in + 8in + 10in = 24in.
