How much should all sides of a triangle equal up to?

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.
