Practice of making angle bisector
The steps of making the angle bisector are as follows:

Need to find a corner. This angle can be a triangle angle, a rectangle angle, or even an arbitrary angle. You need to put a ruler on the vertex of this corner. This ruler is like a dividing line, which can help us divide the corner into two equal parts.

We draw two rays on both sides of this corner with a pen. These two rays will meet at the vertex of this angle. In this way, we get a separation point This point is the bisector of the angle. We need to mark this bisector. We can use an arrow to indicate the opening direction of the corner.

According to the geometric principle, the bisector of the angle thus made divides the original angle into two equal angles. The bisector is widely used. For example, in the geometric proof problem, congruent triangles can use bisector to construct, thus solving some proof problems.

The benefits of learning mathematics:

1, problem-solving ability

Mathematics is a kind of training in logic and analysis, which is very useful for solving various practical problems. Whether it is scientific research, engineering design, financial analysis or daily life, it is necessary to apply mathematical principles and methods. Through mathematics, we can learn how to break complex problems into smaller and more manageable parts and then solve them one by one.

2, the improvement of thinking ability

Mathematics can train our thinking ability, including logical reasoning, inductive classification and reduction. These skills are essential for understanding complex problems and situations and finding solutions. Mathematics can also enhance our critical thinking, because the correctness of mathematical conclusions needs strict reasoning and verification.

3, it is widely used

Mathematics is widely used in various fields. For example, physics, computer science, economics and statistics are all inseparable from mathematics. By studying mathematics, we can better understand the basic principles and methods of these disciplines. At the same time, mathematics also plays an important role in practical fields such as engineering, science and commerce, such as designing algorithms, statistically analyzing data and optimizing production processes.
