Simple explanation of this nice fact from math. Math can be sometimes surprising, as well as elegant and pretty. Understanding this common geometric equation will help you out tremendously in math. The Pythagorean Theorem is basic geometry.

Pythagoras was a smart man, so smart that his mathematical theory is named after him and still used today, more than 2,000 years later: the Pythagorean theorem. It implies that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two ...more

A pyramid is a three dimensional figure with the base in the form of a triangle and three slant sides to it. To find the surface area of a pyramid you have to find the area of the different pieces that make it up. The pyramid base can be triangle or even other geometric figure ...more

Math always seems hardest until someone shows you how to do the problem and then it all seems just so simple. This video will walk you through the process of finding the surface area of a cone when you also have to derive the slant height. Use this example to help with your ot ...more

The Pythagorean theorem is a simple theorem that states that - for a right angled triangle the square of the length of the hypotenuse is equal to the sum of the squares of the length of the remaining two sides. In this video, a right angled triangle with three sides, namely a ...more

The video describes the "Calculation of the surface area of the cone without a slant". If the base circle diameter (d) and the height of the cone (h) are known, then the following procedure can be used for finding out the surface area oh the cone: Surface area of the cone is ...more

Can you dissect an equilateral triangle into pieces that can be rearranged into a square? If you think you can, you may have mastered the Pythagorean theorem. Can you figure out how to draw a straight line without a reference edge? If so, you might just be the pioneer of the ...more

The video shows us how to find the area of parallelogram using geometry. Here in this video it is done by using an example where the parallelogram is given ABCD. The area of the parallelogram is base times height (bh). Here the base is given as 15 but the height is not known b ...more

This video shows how to compute the area of a rectangle given the length of one of its sides and its diagonal. First start by drawing the picture of the rectangle. Now draw the diagonal and label the known lengths. In the diagram, the diagonal and two sides of the rectangle fo ...more

Imagine two stakes in your backyard. Now draw an east-west, north-south coordinate system on your lawn. Measure the east-west distance between the stakes and also the north-south distance. Take the square root of the sum of the squares of the two measurements and, voilà, you e ...more

The Pythagorean Theory is a way to find the missing length of a right triangle. Here is a right triangle with a description. The Formula for Pythagorean's Theory is A squared + B squared = C squared. If the hypotenuse is missing then you would use the formula above. If one of ...more

As sure as death and taxes, sitting at a wobbly table at one time or another is inescapable. With your weight on it, the table shifts from one end to the other, lifting one leg in the air and then the other; a parade of seesaws, especially if you have someone sitting on the ot ...more
