Quadrantal angles (0, 90, 180, and 270 degrees), and the values of the sine, cosine, and tangent of each of these angles. From the trig lessons in the Algebra 2 course by Derek Owens.
If that first angle is 130 degrees and the two small corners are 20 degrees, when we make those last two lines meet, the angle has to be 190 degrees. 130 + 20 + 20 + 190 = 360. No matter how you change the angles, they always add up to 360. The Perimeter of Any Quadrilateral is just the sum of the four sides. In this quadrilateral, the sides, in inches, are 4, 4, 5 and 2. Therefore, the perimeter is 4 + 4 + 5 + 2, or 15 inches.
