Philip Carret, who wrote The Art of Speculation (1930), believed âmotiveâ was the test for determining the difference between investment and speculation. âThe man who bought United States Steel at 60 in 1915 in anticipation of selling at a profit is a speculator.
The formula for finding the total measure of all interior angles in a polygon is (âânââ â 2) x 180, where âânââ is the number of sides, as well as the number of angles, the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.
You can easily use a ruler to find the approximate perimeter of a polygon. If you already know the length of each side of your polygon, skip Step 2 and proceed to Step 3. Use your ruler to measure the length of each side of the polygon. Write down the length of each side.f you already know the length and the width of the rectangle, use this formula to find the perimeter. Parallelogram: Perimeter = (2 x a) + (2 x b). Like rectangles, parallelograms have two sets of parallel sides that are the same.
