So it's 1 2 ab.

Uh, it's a triangle.

Flatland is populated by geometric shapes, ranging from isosceles trianges to equilateral triangles to squares, pentagons, hexagons, all the way up to circles.

Let me draw it a little bit neater than that.

Triangle

Equilateral Triangle

And then we have something interesting

We're on problem 15.

Triangle ABC equals Triangle Aprime, Bprime, Cprime.

Three sided cells

So let's see if we can do the same with triangles.

This line is a perpendicular bisector of AB, and so we have two right triangles

So we have the focal length.

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

Select this Rational Bézier Cubic

Select this triangle

Remove a Triangle

Add a Triangle

Move a Triangle

Show a Triangle

Hide a Triangle

Triangular pyramid

These triangles are similar.

And how about the Bermuda Triangle? You're not going to deny... I am.

And then what you can see is both of the triangles and when I say both of the triangles

Geometric Right Angle Triangle

Geometric Isosceles Triangle

And then we see that triangle AEC must be congruent to triangle DEB by side angle side

Let me draw my right triangle just like that.

How do I know it's not 15 or 16?

A very fancy word for a very simple idea.

So, we now know that the triangle, I'll keep this in yellow, triangle AEB is congruent to triangle DEC by side angle side congruency, by SAS congruent triangles

Here's the code for defining the geometry for two steps. The way cube geometry works is that you provide it a size in x, y and z.

smooth triangle

And then we went to the side the aim of the vertex is not labeled

And it deals with right triangles.

There's a simple piece of math that relates all of those 4 variables over here, and it's easily obtained by what's called equal triangles.

Let's do some solid geometry and volume problems. so they tell us shown is a triangular prism. and so there's a couple of types of three dimensional figures that deal with triangles.

Select the triangle that has to be transformed onto a given triangle...

Map this triangle

Яагаад гэвэл гурвалжины нийт өнцгүүд 180 градус байдаг.

35 is our c.

Now the other interesting thing on each of these ,we have an angle and we have a side, each of these triangles
