measure with an protacter
Sum of dimensions of all sides
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.
Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.
A triangle.
So the line that make the perimeter can enclose a space.
measure with an protacter
yes
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.
Sum of dimensions of all sides
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
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.

I think a trianglE
Figure it out yourself
Scalene triangle
That is a triangle.
