轴线角和区域角的表示是进入高一下学期就会遇到的重难点问题。本文拟从其几何意义角度来举例说明其应用。我们知道,轴线角和区域角的表示都是通过终边相同的角的规律来处理的,由角的概念不难得到其几何意义。1.与角α的终边相同的角的集合是S={β|β=α+k.360°,k∈z},β=α+k Axis angle and regional angle that is entered into the high semester will encounter heavy and difficult issues. This article intends to illustrate its application from the perspective of its geometric meaning. We know that both the axis angle and the area angle are handled by the law of the same angle at the end. The concept of angle is not hard to get its geometric meaning. 1. The same set of angles as the end of angle α is S = {β | β = α + k.360 °, k∈z}, β = α + k
