Statement right here is triangle BAF triangle BAF

Geometric Right Angle Triangle

It's a right triangle.

One Staple Angled

larger triangle right up there

This is a right triangle.

So this is a right triangle.

So this is a right triangle.

Say we have a right triangle.

Let's draw an arbitrary triangle right over here. now let's say that is our triangle.

So a right triangle is a triangle that has a 90 degree angle in it.

It's a right triangle, let me put some

And since that is a triangle that has a 90 degree angle, it's a right triangle.

Remove select? Or remove the angled braces?

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

BAF so that's this entire triangle right over here

Let me draw my right triangle just like that.

So let's say I have the following right triangle.

And then, in 20 minutes, the right angled triangles began to appear on the screens.

Triangle ABC equals Triangle Aprime, Bprime, Cprime.

smooth triangle

Equilateral Triangle

Triangle. Doctor

And this is a very typical type of right triangle.

So as I mentioned already, this is a right triangle.

So let's look at this first triangle right over here.

And the Pythagorean theorem tells us that if we're dealing with a right triangle let me write that down if we're dealing with a right triangle not a wrong triangle if we're dealing with a right triangle, which is a triangle that has a right angle, or a 90 degree angle in it, then the relationship between their sides is this.

So let me draw some right triangles, let me just draw one right triangle.

You only have a hypotenuse when you have a right triangle.
