Bisecting line AB into 17.7 cm results in two equal halves, each measuring 8.85 cm. If "17.7 cm into 1" refers to the entire length, then the answer is 17.7 cm.
To bisect line AB into 17.7 cm, you can follow these steps:
Draw line AB with the desired length.
Place the compass point on point A and extend the compass to a length greater than half of AB. In this case, extend it to a length slightly longer than 8.85 cm.
Without changing the compass width, draw an arc above and below line AB. Label the intersections with the arc as C and D.
Connect points C and D to point A. The line CD should intersect line AB.
The point of intersection (E) divides line AB into two equal halves.
Now, for the second part of your question, "17.7 cm into 1" is not entirely clear. If you mean dividing 17.7 cm into 1 equal part, it essentially means the whole length is considered as one part, so you have the entire length of 17.7 cm.
In summary, to bisect line AB into 17.7 cm, follow the steps above, and the final length of each half will be 8.85 cm. If "17.7 cm into 1" refers to the entire length, then the answer is 17.7 cm.
