You find the three sides of the triangle, and assure that they are all in the same unit, and then add the sides together to find the perimeter of the triangle.
They don't always- they don't always 'has' a smaller perimeter than other triangles. A triangle can be absolutely any size as long as it has three sides and angles that add to 180 degrees

The perimeter of any triangle is the sum of its 3 sides
An infinite number are possible.

Infinitely many.

you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
An infinite number are possible.

You can't tell. There are an infinite number of triangles that all have a perimeter of 144.
to measure the perimeter we need a figure with boundaries and all the sides with dimensions
You simply just add up all of the sides

The perimeter is the measure of length of the boundary of a 2-dimensional object. The most common mathematical objects in this category are squares, rectangles, circles and triangles. The perimeter of a square = 4d (where d is the length of 1 side) The perimeter of a rectangle = 2l + 2w (where l is the length and w is the width) The perimeter of a circle = 2πr (where π is the mathematical constant pi and r is the radius. The perimeter of a circle is better known as the circumference) The perimeter of a triangle is the total length of all three sides.
