In this video tutorial the author shows how to find the perimeter and area of a complex figure. He shows that a complex figure can be subdivided into standard geometric figures. In the current example he divides the complex figure into a rectangle and a triangle. Now he computes the perimeter by adding the three sides of the rectangle and the two sides of the triangle. Similarly he computes the individual areas of the rectangle and the triangle and finally adds then up to find the area of the...
In this tutorial the instructor shows how to compute the area of irregular shapes. He demonstrates this with an example showing an irregular area and says that as there is no direct formula to calculate it, you need to break up the irregular area into identifiable simple geometric figures. He goes on and breaks the irregular shape into a square, a triangle and a trapezoid. Now he computes the individual areas using a standard formula and sums them up to arrive at the final complete area of th...

There wouldn't be any chaos in the world without Benoit Mandelbort— chaos theory, that is. Mandelbrot, who just passed away at the age of 85, pioneered fractal geometry and greatly influenced chaos theory. He spent most of his life working in physics, biology and astronomy, and is best known for his Mandelbrot Set, a mathematical set of points in the complex plane (the boundary of which forms a fractal).

One of the most popular and basic origami geometric shapes is the "water bomb," which is a simple inflated cube. With a few extra folds and only a minor shift in approach, a more complex geometric shape can be achieved.
The video shows us how to find the area of triangles and other geometric shapes. First, before starting to find the areas, we need to know the basics of what do those shapes actually mean and we need a little bit of vocabulary to back us up. First, the parallelograms are four sided figures with two sets of sides which are parallel to each other. The rectangles and the squares qualifies the parallelograms and also the parallelograms except that they have slanted sides and the triangles are thr...
Finding a unique wallpaper can be extremely difficult, and even the most dynamic wallpapers become exhausted and boring to look at after a while. Searching for new, interesting wallpapers can become a tedious task, so instead, let's just make our own instead.

The paperless office is as much of a myth as the paperless toilet, so accept it, if you are serious about business, you need paper. Important contracts between customers signed on papers, leaflets, reminders, advert previews, drafts for preview at the table. The paper is always used even in today highly computerized epoch.
Cavandoli Macrame (also called Tapestry Knotting) is an intricate form of knotting used to create geometric patterns. The Cavandoli style is done mainly in a single knot, the double half-hitch knot. Reverse half hitches are sometimes used to maintain balance when working left and right halves of a balanced piece.
Concrete decor has been popular as of late, and the newest trend is dinnerware.

A while back, I wrote review of my favorite hacking movies of all time. Two of my key criteria were; (1) how realistic was the hacking, and (2) are the hackers portrayed as the "good guys." This past winter, a new hacker movie was released, appropriately named Blackhat starring Chris Hemsworth (from Thor fame) as a blackhat hacker who is released from prison to stop a notorious and destructive hacker that only he can stop. Although the movie did very poorly at the box office, I thought it was...
