There is 1 right angle and 2 acute angles on the block triangular ruler.
Both acute angles of the isosceles right-angle triangular ruler are 45°. Two identical isosceles right triangles can be put together into a square, or they can be put together into a larger isosceles right triangle.
The two right-angled sides of an isosceles right-angled triangular ruler are equal in length.
The acute angles of the slender triangular rulers are 30° and 60°, respectively. Two identical slender triangular rulers can be put together to form a regular triangle.
The hypotenuse of a thin triangular ruler.
The length is twice the length of the short right-angled edge.

There are two types of triangular rulers.
1. Isosceles triangular ruler (the smaller one): both bottom angles are 45 degrees, and the top angle is 90 degrees.
2. The other (the larger one): one angle is 90 degrees, the other two angles are, the larger one is 60 degrees, and the smaller one is 40 degrees.

What is the angle and what degree is the three corners of any triangle cut or torn out and put together?

The three corners of the triangular ruler are: 1 right angle and 2 acute angles.
A triangular ruler, also known as a triangular board, is a commonly used drawing tool. The triangular ruler has three corners and three sides, and each triangular ruler is composed of two special right-angled triangles. One is an isosceles right-angled triangular ruler and the other is a right-angled triangular ruler with special angles.
1. The two acute angles of the isosceles right-angled triangular ruler are 45°, and two identical isosceles right-angled triangular rulers can be put together into a square, or they can be spelled into a larger isosceles right-angled triangle, and the length of the two right-angled sides of the isosceles right-angled triangular ruler is equal.
2. The acute angles of the slender triangle ruler are 30 ° and 60 ° respectively, and two identical slender triangle rulers can be put together into a regular triangle, and the hypotenuse length of the slender triangle ruler is twice the length of the short right-angled side.
3. Use a triangular ruler to easily draw an integer multiple angle of 15°. In particular, a triangular ruler and a T-ruler can be combined to draw a series of vertical lines in a bottom-up order. Matching a T-ruler with a triangular ruler allows you to draw an angle of °.
4. With two triangular rulers and T-shaped rulers, you can also draw the oblique line of °, with two triangular rulers, you can draw the parallel lines of any drawing line, and the two triangular rulers can be pieced together to draw angles of 135°, 120°, 150°, 75° and 105°.
