Draw An Arc Or Circle With an ABS Compass
Using an ABS compass to draw a circle or arc is the main function of a circle gauge, specifically by
1. Use a ruler to measure the distance between the two feet of the circle gauge as the radius.
2. Fix the end with the needle in one place as the center of the circle.
3. Drop the end with the pencil on the paper, lift the upper end of the circle gauge, and gently rotate it to the desired position, which is the arc, and if you rotate it for a week, a circle is drawn.
Intercepting a Line Segment With an ABS Compass
1. First draw a ray with a straightedge.
2. Then use an ABS compass to measure the length.
3. Make an arc with the origin of the ray as the center of the circle. The distance between the origin of the ray and the intersection of the arc and the ray is the length of the intercepted line segment.
Use an ABS Compass To Equate Line Segments
1. Using each of the two endpoints of the line segment as the center of the circle and the length of the line segment as the radius, draw two circular arcs with an ABS compass.
2. The two arcs intersect at two points outside the line segment.
3. Connect these two points to make a straight line, the point where this line intersects with the original line segment is the equidistant point of the original line segment.
