1. Preparation materials: paper, pencil, marker, ruler, eraser, etc. Layout planning: Sketch the general layout of handwritten newspaper on paper with pencil, including title, definition of angle, nature of angle, classification of angle and so on. Draw a title: Write "Understanding of Corner" as the title with a colored pen or marker in large font.

2. Definition of drawing a corner: In the corner of the handwritten newspaper, describe the definition of the corner in concise and clear language, for example, "The part where the starting points of two rays are the same is called the corner." Arrows can be used to indicate the starting and ending points of light. Draw the nature of the corner: in the other corner of the handwritten newspaper, show the nature of the corner with pictures and texts.

3. Classification of drawing angles: In other parts of handwritten newspaper, draw different types of angles with different colors and shapes, such as acute angle, right angle and obtuse angle. You can use icons and words to explain the characteristics and definitions of each angle.

Related knowledge of angles in mathematics

1. The angle in mathematics is a geometric quantity that describes the intersection or non-intersection of two rays or line segments on the same line. Angles can be divided into acute angle, right angle, obtuse angle, right angle and rounded corner, among which acute angle, right angle and straight angle are three common angles.

2. Acute angle refers to an angle less than 90 degrees, which can be expressed by any angle less than 90 degrees. A right angle is an angle equal to 90 degrees, usually represented by a vertical line segment. An obtuse angle refers to an angle greater than 90 degrees but less than 180 degrees, and can be expressed by any angle greater than 90 degrees but less than 180 degrees. A flat angle is an angle equal to 180 degrees, which is usually represented by a straight line.

3. In addition to the above three common angles, there are many other types of angles in mathematics. Such as adjacent complementary angle, antipodal angle, internal dislocation angle, congruent angle, etc. These different types of angles have different properties and applications in solving mathematical problems.

4. Adjacent complementary angles refer to two adjacent angles, and the degree of one angle is the degree of the complementary angle of the other angle. The antipodal angle refers to a figure composed of two intersecting line segments or rays, and the two diagonal angles are equal. Internal dislocation angle means that in a graph composed of two disjoint line segments or rays, the two diagonals are equal. An isosceles angle refers to two angles with the same relative position.
