The question is:,
What is, obtuse triangle?
An obtuse triangle is,
A triangle, that, possesses one angle, which is larger than, ninety degree.
As shown in this figure, the obtuse triangle, A, B, C, has an angle, which is larger than 90 degrees, on the edge, B,

In general, The area of, any triangle, is expressed as, a half, times, height, and base.
Moreover, the height, must be perpendicular, to the base, as shown in the figure.
This was discussed, in our previous video.
Please fine the link, to the previous video, somewhere on the monitor, or in the description below.

The question is,
Whether or not, this formula, is applicable, for the case of, obtuse triangle.

As far as the conclusion is concerned, the answer is, yes.
The proof will be presented, throughout this video.
So, stay tuned, and please subscribe.

The calculation of the area, of obtuse triangle, is actually, based on, that, of, right triangle.
The proof of, The area of, right triangle, was discussed, in our previous video.
Please fine the link, to the previous video, somewhere on the monitor, or in the description below.

First, let us put, a small, right triangle, to the left of, obtuse triangle, A, B, C,.
Let us call, this small, right triangle as, B, C, P,.
Please see the figure, for better understanding.
This combination, resulted in, a larger, right triangle.
Let us call, the larger triangle as, triangle, A, C, P.
