Understanding Corner PPT, Part 2: Exploring New Knowledge

Knowledge point Compare the size of angles

Cut out the two corners of Figure 1 on Appendix 3, compare them, and draw a "√" on the larger one.

As shown in the picture, compare the sizes of the corners of the two triangles. What do you find?

The three angles of the two triangles coincide with each other, indicating that their corresponding angles are equal.

The size of the horn has nothing to do with the length of the side, only the size of the mouth.

Knowledge refining

The size of the angle has nothing to do with the length of the two sides of the angle, but is related to the size of the opening of the two sides of the angle. The larger the opening, the larger the angle.
