A scalene triangle is a 80 triangle,in rare casses it can be 90 degrees.
the sum of the internal angles of a triangle, no matter whether isosceles, equilateral or scalene, is always 180 degrees
Never
And Equilateral Triangle has three EQUAL sides. Basically just your ordinary triangle. The Isosceles triangle usually has TWO equal sides, and one odd side,( not the same size in degrees.) A scalene Triangle also has TWO of the same sides, BUT- Its degrees are usually always different. I'll show you some examples. The first example below is an isosceles Triangle. The 2nd is the Scalene Triangle... Hope I helped...
No. An isosceles has two equal sides and two equal angles. A scalene has no equal sides and no equal angles.
