If you know any two angles and a side, you can use the law of sine (or law of cosine) to find the other two sides, add them up and get the perimeter. It you know the base and height, you can use the Pythagorean Theorem to get the side lengths, add them up and get the perimeter.

Why is finding the perimeter of a triangle related to finding the perimeter of a rectangle?
It is not in all but a trivial sense - that they are both to do with finding the perimeter!
What is the formula for finding the perimeter of a triangle when given the base and the height?
You multiply the base and the height and then you divide the answers of that by 2. :)
How do you find the area of a triangle by Heron's formula?
For finding the area of triangle with the help of Heron's formula: [s(s-a)(s-b)(s-c)]1/2 where a,b,c are sides of the triangle and s=1/2 of perimeter of the triangle
Perimeter formula of a triangle?
The perimeter formula of a triangle is the sum of the lengths of all three sides. Mathematically, it can be expressed as P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the three sides of the triangle.
What is the formula of a triangle in perimeter?
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
What is the formula of finding the perimeter of triangle?
the formula is 1side multiply by 3
What is formula of finding the perimeter of a triangle?
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
What is the formula for finding the perimeter of a triangle?
you add the sides together . a /\b a+b+c /_\ c
