In this video we learn how to fold a very simple paper football. First, take a piece of paper and cut out a strip from it or fold it into a strip. After this, fold a triangle in the strip of paper. Once you have this, fold up to create another triangle and keep folding up until you reach the top of the strip. There will be one small piece of excess paper left on the strip. You can either cut this off or tuck it into the pocket that you made while folding the triangles. Use this to pass the ti...
In this video we learn how to craft a paper football. First, take a sheet of paper and cut it into a strip. After this, take the strip and fold down the top into a triangle. Then, continue to fold the triangle down until you reach the end of the strip. You will have an extra flap of paper left at the bottom of the strip.

In this tutorial, we learn how to find the interior and exterior angles of a triangle. I triangle has three angles and their measurement when added together will equal 180. For example, if one angle is 80 and another is 30, then start off saying the equation equals 180. Write in 80+30+X in front of the equals sign, then subtract the combined like terms from the 180. After this, you will have found the value of x, which will also be the measurement of the last angle. Make sure to write out the...

This video is about deriving the area of a circle of radius 'r' using polar co-ordinate. First, we draw a circle and its radius 'r'. Then draw another radius close to it, so that it forms a small triangle-like figure. To find the area of the complete circle, divide the circle into similar small triangles. The area of each triangle is given by half the product of its perpendicular and the base. We give the angle between the two radii as d?. We get the area of the small triangle by substituting...
Three students demonstrate how to fold an American flag. Two students hold the flag lengthwise, flat. They fold the flag in half with the stars on the bottom of the fold. Then they fold the flag a second time, gently pulling it taut. A third student keeps her arms under the flag as one of the students begin to fold small triangles down the length of the flag towards the student at the other end. The purpose of the third student is to keep the flag from falling. When the flag has been folded i...
This is a very interesting instructional video on how to fill a cone. Pour oil into a cone of diameter 30 inches and depth 40 inches. Now find the volume of the oil as a function of its depth. Volume = 1 over 3 phi rsquare h. We don't know the height and depth of the oil poured into the cube. Draw similar right angled triangles. In one right angled triangle the height is 40 inches and in the other triangle it is h. Similarly the height is 40 inches and h respectively. Now rover h =15 over 40....

When you are figuring the area of a square, you only need to know the height and width of the shape. Once you know the height and width, multiply them to get the area of the square. To find the perimeter of the square, add all four sides together. To find the area of a triangle, multiply together two of the sides (not the hypotenuse) and then multiply that figure by 1/2. To find the perimeter of the triangle, add all three sides together.
In order to find the cosine of a triangle in trigonometry, you will need to understand the CAH formula, part of the larger mnemonic of SOHCAHTOA, which outlines how to find the sine, cosine, and the tangent of an angle.

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...
