Examples include triangles, quadrilaterals, pentagons, hexagons and so on. Regular Here we will be looking at Regular Polygons only. Properties So what can we know about regular polygons? Example: What is the exterior angle of a regular octagon? An octagon has 8 sides, so: Exterior angle = 360°/n = 360°/8 = 45° Interior Angle = 180° - Exterior Angle We know the Exterior angle = 360°/n, so: Interior Angle = 180° - 360°/n Interior Angle = (n-2) × 180° / n Example: What is the interior angle of a regular octagon? Example: What are the interior and exterior angles of a regular hexagon? A regular hexagon has 6 sides, so: Exterior Angle = 360° / 6 = 60° Interior Angle = 180° - 60° = 120° And now for some names: "Circumcircle, Incircle, Radius and Apothem ..." Sounds quite musical if you repeat it a few times, but they are just the names of the "outer" and "inner" circles (and each radius) that can be drawn on a polygon like this: Graph
'Pride and Prejudice' has been reimagined as a computer game - with Elizabeth Bennet constantly on the run through the classic text - Gaming - Gadgets & Tech The fault, you see, lay not in the book, but its method of delivery: It was presented by a new video game, Stride & Prejudice, which is "an endless runner based on Pride and Prejudice by Jane Austen", according to its tagline. This isn't your usual "based on" video-game adaptation of literature, such as the 2010 hack'n'slash inspired by Dante's Inferno, or the interactive version of The Great Gatsby (see below). In Stride & Prejudice, the book is the game, its words forming a steady succession of platforms that your character, Elizabeth Bennet, runs and jumps across. Stride & Prejudice offers two ways to play. It is a truth universally acknowledged, [tap the screen, Ryan!] that a single man in possession [tap now!] of a good fortune, [jump!] must be in want of a wife. What keeps Stride & Prejudice from being just an, ahem, novel take on the endless runner, though, is reader mode, in which you can "die" infinite times and Elizabeth will reincarnate where she left off. "Books – Oh! Some.
Converting audio cassette tapes to CD, MP3 and other digital formats See more Audacity questions and answers at the Audacity Q&A. My parents recently redecorated a room in their house. While cleaning up, they found a cassette tape wedged in a back corner, covered in thick layers of time and memory. Just looking at it, you could tell it was old: The label, originally red and white, was now pink and brown. The tape rattled if you shook it gently, not a good sign. With the luck of having such an old tape still work, and containing rare audio of the mid-eighties, we needed to get this tape copied fast. What you need You'll need a cassette tape player with a headphone jack, a computer with a soundcard, the free "Audacity" software, and a 3.5mm (1/8-inch) male-male stereo audio cable. How to convert 1) Plug one end of the audio cable into your cassette player's headphone or "Line out" jack, and the other end into your computer soundcard's "Microphone" or "Line in" jack. 3) Press the record button (red circle) on Audacity, then press play on your cassette tape.

I’ll Never Ever Look At Books The Same Again After Seeing These Hidden Messages. Wow. It’s very possible that one of your battered old books contains an amazing secret called a “fore-edge painting,” which is an illustration that is hidden on the edge of the pages of the book. The technique allegedly dates back to the 1650s. You can see the painting by bending together the pages of the book, just so you can see a small piece of each page. Autumn by Robert Mudie / Special Collections & University Archives at the University of Iowa So much time and dedication was put into this, the results speak for themselves. Winter by Robert Mudie / Special Collections & University Archives at the University of Iowa There are even books that have double fore-edge paintings, where a different image can be seen by flipping the book over and fanning the pages in the opposite direction.

Sita Sings the Blues This physics grad student made a mind-blowing Bohemian Rhapsody cover I agree. It should be yarn, obviously. Also, the Big Bang sounds like the current equivalent of the turtle swimming in an eternal sea. On his back there are four pillars. Atop the pillars is an elephant, and carried on the elephant's back is the half-globe that is our world. Nobody's been able to answer to my satisfaction the question of what banged, and where the hell it came from. Presuming that wasn't meant to be taken satirically, it's not as much a big bang as it is a rewinding of the tape thing, we know the universe is expanding, so we presume it had to have had a point were it started expanding, now into what it is expanding, and from were the original energy came from, those are still unanswered questions. Then read Lawrence Krauss's book "A Universe from Nothing: Why There is Something Rather Than Nothing." Sometimes things just happen what the hay.
