Where is the 60 degrees of the triangular ruler and what is the degree of the triangular ruler?

The slender triangle ruler is 60° in addition to the right angle of 90° and the smallest acute angle of 30°, as shown in this picture.

A triangular ruler has 1 right angle and 2 acute angles. One of the triangles is ° and the other is °.

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.

Triangular Ruler Mapping Application:

1. Use a triangular ruler to easily draw an integer multiple 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 °. Diagonal lines are usually drawn from left to right when drawing. You can also draw a diagonal line of ° with two triangular rulers in conjunction with a T-ruler.

2. With the cooperation of two triangular rulers, you can draw the parallel lines of any drawing line.

3. Two triangular rulers can be pieced together to draw angles of 135°, 120°, 150°, 75° and 105°.

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

To draw an 80° angle with a triangular ruler, first draw a 60° angle with a right-angled triangular ruler containing 60 degrees, take an equal length line segment on the two sides of the angle, and connect the two points on the side to form an isosceles triangle. Then divide the bottom edge into thirds, and then connect the vertices with the thirds, exactly 3 equal parts the 60° angle, and each small angle is 20°. Then draw a 60° angle with a triangular ruler on one side of the 20° angle, and the 20° and 60° together are 80°.

Related information. 1. The simplest is to draw a ray with a triangular ruler first, and the center point of the protractor and the end point of the ray coincide. 0 tick marks and rays coincide, point on the scale of 80 degrees of the protractor, pass the end of the ray and the point just made, draw the ray to form an angle of 80 degrees.

2. The triangular ruler has three corners and three sides. Each triangular ruler consists 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.

The degrees of each inner angle of the isosceles right-angled triangular ruler are 90 degrees, 45 degrees, and 45 degrees respectively. The number of each internal angle of the special right-angle triangular ruler is 90 degrees, 60 degrees and 30 degrees, respectively.

3. With the cooperation of two triangular rulers, you can draw the parallel lines of any drawing line. Two triangular rulers can be pieced together to draw an angle of °.
