i believe 160
a triangle could have it sides as anything but all the sides must add up to 180degrees. this was professor liban lol.
There are 3 sides to a triangle and 3 inside angles that add up to 180 degrees The sum of the two shorter sides must be greater than the third side.
we should add all the sides of the triangle
Add all sides together.
yes a scalene triangle is a isosceles triangle.* * * * *No. A scalene triangle is not an isosceles triangle. The sides of a scalene triangle must all be of different lengths. In an isosceles triangle two of the sides must be the same length. If all three sides are different (scalene) then two cannot be the same (isosceles).

180
You add up all of the sides!
There are four types of triangles. For an "equilateral triangle", all sides and angles have to be the same. For an "isosceles triangle", 2 of 3 sides and angles have to be the same. For a "scalene triangle", the "the same" rules don't apply. For a "right-angled triangle", one corner has to be a right angle (90 degrees.) For example in an equilateral triangle, as long as the sides are the same, they can add up to anything. However, angles are different. In any given triangle, the angles must add up to 180 degrees.
The type of triangle whose three sides are all of different length is officially called a scalene triangle.
The sides don't add up to anything but the angles should add up to 180 degree to form right triangle or any other triangle.
-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
