Calculating The Area Of A Parallelogram A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is:
First you want to find X using the identities given for a 45-45-90 triangle. When comparing the triangles in the video, we find that X must be 6. Next, use the identity to solve for the measurements of the sides of the triangle. In the video example, 6 is the length of the two sides and 6 times the square root of 2 is the length of the hypotenuse. The video is very short and does not explain a lot of things in detail, but that is because the examples are easy to figure out.
This video explains to you how to find the area of a square. The area of a square is given by the formula
To find the length of a side of a triangle using cosine, you first need to find the angle and which sides are given. After you determine the angle and given sides, you'll need to figure out which trigonometric ratio to use. If you are given the adjacent side and the hypotenuse, you need to use cosine to solve. The degree equals adjacent divided by hypotenuse. In the example, Cos 39=3.5/x. After simplifying the equation, we found x to be 4.49. If the directions ask you to round, be sure to rou...
In this tutorial the author shows how to find out the missing side of a triangle which is similar to an other triangle. He explains the concept of similar triangle using diagrams and by showing that similar triangles have equal corresponding angles and parallel sides. Now he labels sides of similar triangles and intends to find out the length of unknown side. Now in similar triangles, as the lengths of sides are proportionate he shows how to write a equation of proportion and solve it finding...
For people who are learning geometry and would like to be able to find the perimeter of a rectangle, this video provides and quick and simple tutorial which provides the formula as well as a good example. The formula for finding the perimeter of a rectangle is simple the sum of all sides, or l+l+w+w, where l is the length and w is the width of the rectangle. After attaining the values of the length and width of the rectangle, you can simply plug in the values to this equation in order to find...
The first thing you have to do is draw a line of the same length as the radius of the circle you want to draw. Then, open the compass the same size as the line length you draw is. Rotate the compass and you will create a circle. Please note that drawing this on a single sheet of paper can be difficult because the paper can move. Also, you can try rotating the paper, instead of the compass.
Short homemade video showing how to make a Friendship Flip Flop Zig Zag bracelet. The bracelet is easy enough to be made by a child and the tutorial easy enough for a child to follow.

In this tutorial, the instructor shows how to do a translation in geometry. Now he shows this by using various drawings and by practically explaining it while performing the translation. He first shows how to set up the translation line and now goes on to translate each and every vertex by drawing a parallel line to the translation line through each vertex, which is the same length as the length of the translation line. Now he combines the end points of the translated lines which gives us the...
The video teaches the viewer how to find the area of a parallelogram and the area of a triangle. For a parallelogram, the first step is to find the right angle, the line perpendicular to the base (this is a line you draw, not part of the parallelogram). The height of the line that forms this right angle with the base is the perpendicular height. Next, find the length of the base. The area is the base times the height. For a triangle, find the right angle with the base (again a line you draw)....

Now define the shape as a brush and then click "edit" and "define brush preset" name this, "bokeh"...
Sometimes pills aren't the best answer. Doctors do not need to prescribe medications for common health problems, such as high blood pressure. They can be helped by simple adjusting your lifestyle. If you have high blood pressure, you are more than twice as likely to develop heart disease and six times more likely to have a stroke than people with normal blood pressure. Manage your condition through diet.
