add up all the sides?
A triangle (as you may know) by definiition has 3 sides; if you add up the lengths of all 3 sides, that total is called the perimeter.
Depending on the sizes who knows
They could all be the same length, or two of them could be the same, or they could all be different. In any case, when you add them all up, the number you get is called the "perimeter" of the triangle.
Three sides of equal length and thus all angles are each 60 degrees, because all triangles add up to 180 degrees
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.
180
You add up all of the sides!
The sides of a triangle add up to the perimeter.
i believe 160
-- 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.
a triangle could have it sides as anything but all the sides must add up to 180degrees. this was professor liban lol.

Add up the length of all sides
A triangle with 3 different sides and 3 different acute angles that add up to 180 degrees is a scalene triangle.
