Question 2: Only use compasses and rulers to draw the bisector of the angle, and draw the edge where the circle intersects the angles A and B with the vertex of the first handle angle as the center and the appropriate length as the radius.
Then, take A and B as the center, and draw the vertex and D of the connecting angle where the circle intersects with point D with the same radius.
Is the bisector of the angle.
According to the congruence (SSS) of triangle (da = distance from DB A to vertex = distance from B to vertex; The line segment from d to the vertex is a common edge).
Question 3: How to draw the bisector of the angle with a compass and show me the picture? Just say I don't understand, and I must give wealth value. Urgent!
Question 4: How to draw the bisector of angle with compasses? It is better to draw a straight line on the paper with a picture, take a point as the middle, make the straight line on the compass coincide with it, take 90 degrees as the dividing line, the compass has an angle, and both sides take the same angle. For example, if you need 30 degrees, just find the 30-degree angle of 90 degrees left and right, click a little on the paper and write it down. Finally, take the compass and connect it directly.
