One can't. The angle between those is needed.
If you have the length of each of the three sides of a triangle, you can find the perimeter of (the distance around) the triangle by adding the length of the sides. Their sum will be the perimeter of this geometric shape.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC
you can fine the perimeter
The perimeter of a triangle is simply the sum of the lengths of its three sides. Knowing that it is right angles (or not) is rarely of help.
It depends on what you wish to measure: the lengths of sides, the angles, the area, the perimeter.
The fact that it has a 30 perimeter tells you nothing about the triangle's angles and very little about the lengths of its sides. The name, if it has any, is indeterminate.
The perimeter of a triangle, given only two sides and no information about angles, cannot be determined. However, it can be said (if the two given sides were A and B) that the perimeter cannot be less than 2A or 2B, whichever is more, nor more than 2(A+B). These are limiting cases. In the first case, A or B approaches zero, which makes C approach B or A. In the second case, A and B have an angle approaching 180 degrees, making C approach A+B.
