Select the section. 1. The average score is characterized by the same number of copies per serving.

Practical part. The angle is undetermined, the size is arbitrary, you can draw the angle by the right angle in the triangle, the specific steps:
Draw a (ray) according to the given vertices, so that the vertices of the triangle at right angles coincide with the endpoints in the diagram, and one of the right-angled edges coincides with the (rays).
When drawing an acute angle, take any point within the right angle;When drawing a right angle, take a point on the other straight edge of the triangle;When drawing obtuse angles, take any point outside the right angle.
Take the end point of the ray as the (endpoint), through the (point) just drawn, and then draw a ray, this angle is the angle we want to draw.
