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?

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

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

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.

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

But we want to know the area of the triangle.

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

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

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.

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,

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

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?

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

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

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.

The area of a triangle is just one half of 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.

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.

And just like the situation here, this area under the curve is going to be the distance traveled and lucky for us, this is just going to be a triangle and we know how to figure out the area for a triangle so the area of a triangle (1 2) base height which hopefully makes sense to you because if you just multiply base height you get the area for the entire rectangle, and the triangle is exactly half of that
