If we know the area of this triangle, we know the area of this triangle.

The green triangle the area of the green triangle so 1 2 the sine of x, that's the area of the green triangle it's

That's the area of a triangle.

And what's the area of a triangle?

So what's the area of this triangle?

The area of this triangle is 6.

So what's the area of a triangle?

So what's the area of this triangle?

And now let's take the area of that larger triangle, of this big triangle here.

So the area of that triangle is 6.

So this triangle that I'm tracing in green what is the area of that triangle?

The area of a triangle equals 1 2 ab.

So what's the area of this triangle right there?

Moving along, what about the area of a triangle?

The area of the triangle is 168 square inches.

And so what is the area of the triangle?

Easy to figure out the area of a triangle.

This triangle is congruent to this triangle, so it will have the same area.

Now, what is the area of not that green triangle.

But we want to know the area of the triangle.

So the area of this triangle is exactly 1 2 of the area of that rectangle.

It's going to be equal to the area of triangle ADC plus the area of CBA.

What is the area in square inches of the triangle below.

Let me just give you one more area of a triangle.

So what is the area of this triangle going to be?

1 2 sine of x, that's the area of that green triangle.

But the area of the entire triangle is 2 of these triangles.

And they're both less than the area of this large triangle, right?

So if we want the area of this triangle right over here,

The area of this triangle is 5 times 4 times 1 2.

And now, what's the area of just this right triangle right here?

That's how we minimize the area of the square or the triangle.

The area of a triangle is just one half of base times height

The most dangerous insurgent area is the Sunni Triangle, a mostly Sunni Muslim area just north of Baghdad.

The area of a triangle is equal to 1 2 base times height.

And I were to ask you what is the area of the triangle?

So this is just going to be two times the area of triangle ADC.

The area of the triangle is 30 in 2. Find the height and base.

And this comes to a general formula for the area of an equilateral triangle.

Well, the area of this half triangle, is base times height times 1 2.

So the area of the triangle is equal to this base times that height.

If we care about, if we care about the area triangle GDC

So the combined area, and I'll do it in a bold color, area of both of them, I'll say area combined, that's equal to the area of the square plus the area of the triangle.

Use the formula A 1 2 base times height for the area of a triangle.

And just so you remember, area of a triangle is 1 2 base times height.
