Where does the notch in the triangle come from?

Look at the figure above: the tangent of the sharpest angle of the red triangle is 3 8 (15 40), and the tangent of the minimum angle of the green triangle is 2 5 (16 40), it can be seen that the two angles are not equal, and the gap is very small, the naked eye can not identify, the wrong two angles are regarded as isotopic angles, so the hypotenuse of the red and green triangle is not in a straight line at all, in other words, this is simply a quadrilateral, so the formula of the triangle is not applicable, resulting in this "puzzle". And a triangle in many places is just a small square area of the concave part at the top.

Hehe, it's just a trick.

First of all, the big triangle is a 14x5 triangle.

The following observations of yours may deceive you.

1.The red triangle in the picture above is an 8*3 triangle, which is wrong, because a 14*5 triangle is not similar to an 8*3 triangle.

2.In the same way, the dark green triangle in the picture above is not a 6×2 triangle.

3.If you want to put a 5*3 square in the big triangle in the picture above, in fact, its left top corner does not coincide with the hypotenuse of the triangle, but it just looks like it

Haha, it dawned on you.

Hurry up and sweat, I have a question to mention, and now I just lack points, hurry up and earn some points.

There is a problem with the hypotenuse of the triangle.

The ratio of the two feet of the red triangle is 3:8 and the green triangle is 2:5

So the hypotenuse is not a straight line, and the two big ones are not actually triangular.

The pre-respell and post-respell are not triangles.

There is a small gap, and when it is torn, the gravitational force is concentrated at the notch, and it is easy to be torn apart. (Solving the equations of elasticity shows this explicitly, and the tensile stress at the notch is n times higher than at the other locations.)

Paste an introduction to the connection of stress concentration.

That's called "dumbfounded".

A lot of things are there.

The main purpose is to help you know the pros and cons quickly.

For example, the triangle notch on the SD card.

Notch in memory.

That's the positioning notch, otherwise it's easy to install the card in reverse. If the mobile phone card has a direction, if it is rectangular, it is difficult to distinguish the direction. It's not okay to pretend to be reversed.

The triangle has stability, and the metaphor of love without a gap is to say that love should be stable and have no regrets (cracks).

GAC Changfeng , what you see is the Jeep of the Cheetah, right?

Peak's sneakers have a very durable sole.

It's fine with the Direct Selection tool, you probably use the Transform Point tool and it will become round.

To put it simply, use a triangle to delete the top one, add a triangle to the bottom one, and use a straw to make the color the same. The Polygon tool can be used to draw triangles.

Draw a rectangle to fill.

Continue with this layer and draw a triangle with the Pen Tool. It becomes a selection and deletes. That's it.
