Jan 15, 2021 · A five-pointed star. Here is the first question, which was actually the second of two submitted at about the same time: This one is hard question, no angles given. We are supposed to find the sum of angles “A”, “B”, “C”, “D” and “E”.
The angle in any point (or tip) of the star is 36 degrees. If you bisect the angle in any point (split it in half), each angle is 18 degrees. Because this angle is always the same, given only the measurement along one of the outer sides of the star, as long as it is a Symmetrical Star, you can calculate the other dimensions.
