How To: Find the area of a right triangle using simple math

It is easy to find out that right triangle is only half of the square. And again there is a rectangle with a triangle shaded in red color. The red triangle is half the area of the rectangle. But to calculate just the area of triangle, we can calculate the area of the rectangle whose area is length times width. When we have a rectangle with its length and width as 4u and 2u respectively then the area of that rectangle will be equal to 8u(squared). But we already know that the triangle is half ...

How To: Perform the green triangle yo-yo trick

This is a demonstration of performing the green triangle yo-yo trick. You can start with a trapeze, lift your non throw hand middle finger and swing the yo-yo off the trapeze. Take care that you do not drop the yo-yo, you can use the middle finger to hold the string. Swing just like doing the trapeze so that the string lands at your wrist. Slide your throw hand out of the loop and you will form the green triangle. To dismount pop the yo-yo out of the green triangle and land on the string near...

This video helps us learn how to make a well-balanced paper football. Get a square paper. Fold the paper in half. Fold it again in the same direction. Fold the paper diagonally to make a triangle. Flip the triangle up so the point lines up with the left edge. Continue folding triangles up the paper until you reach near the top. Fold the top corner down so that the two points meet, making a triangle in the opposite direction. Tuck the extra paper into the pocket. Now you have a paper football.

How To: Find the area of a parallelogram and a triangle

This video shows you how to easily find the area of a parallelogram and the area of a triangle. The first part of the video teaches you how to find the area of a paralellogram. The area of a parallelogram is BxH, where B is the base and H is the height. The height is obtained by drawing a perpendicular line from one corner to the base. The second part of the video teaches you how to find the area of a triangle. The area of a triangle is (BxH)/2, where B is the base and H is the height. That's...

How To: Find the area of rectangles, triangles & rectangles

In this tutorial the author shows how to find the area of Rectangles, Triangles and Parallelograms. He says that an area of a figure is nothing but the amount of space taken up by that figure. He now explains that the area of rectangle is length times the breadth. He demonstrates it with an example. Now he says that an area of a parallelogram is base times height.

How To: Find the sides of a 45-45-90 right triangle

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.

How To: Find the area of a triangle when given 2 sides & angle

This video shows you how to easily find the area of a triangle when you know the length of 2 sides and the angle between them. The first thing you have to do is mark the sides of the triangle by a, b, c, where a is the side between A and B, b is the side between B and C and c is the side between C and A. If you know 2 of these 3 sides an you know the angle between them you can find the area of the triangle very simple: Area= (a x b x sin c)/2, where a, b are the two sides and c is the angle b...

How To: Find the areas of a parallelogram and a triangle

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)....
