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 ...

Then you will need to draw a third and final triangle for the bottom of your tree. Make sure that this triangle is bigger than your first and second triangles. Make the bases of the triangles wavy so that they resemble branches. Add the base by adding a small rectangle and a circle for the stand....
Free Math Tutoring teaches you in this video how to calculate the area of a triangle using a basic formula. The area of a triangle is (b times h)/2. B is the base of the triangle and h is the height. This formula works for all kinds of triangles. Sometimes you won't have the height in the triangle, so you need to draw a line from one angle to the base opposite that, at a 90 degree angle. Measure that and you have your height. It might seem difficult at first, but practice helps you understand...
The area of a polygon is the number of square units inside that polygon. Area is 2-dimensional like a carpet or an area rug. A triangle is a three-sided polygon. We will look at several types of triangles in this lesson. To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area ...

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.
Are math problems getting you down? Well this should be of some help. Here is how to find a missing angle inside of a triangle. Now the first thing to remember when solving this type of question is that the sum of all the three angles inside a triangle is equal to 180 degrees. Therefore, whenever we have two of the three angles inside the triangle, all we have to do in order to obtain the missing angle is to add up the two known angles and subtract the total from 180 and we will get the missi...
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...

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)....
