How do you draw a sector that is half the length of its arc?

There are a couple approaches that could work for creating a sector with half of the arc of the sector shown. Here are three alternatives:

1. Using a protractor,

a. Determine the angle of the given sector.

b. Half the angle is obtained by dividing the angle measurement by two.

c. With the half angle measurement, draw an arc with the protractor.

d. To build the sector, connect the arc's endpoints to the circle's center.

2. Make use of a compass:

a. Set the compass to the supplied arc length.

b. Draw an arc over the sector using the compass point at one end of the arc.

c. Place the compass point at the opposite end of the arc and draw another arc over the sector without modifying the compass width.

d. To build the sector, connect the arcs' endpoints to the circle's center.

3. Use the following formula:

a. Determine the radius of the specified sector.

b. Determine the length of the specified arc.

c. Determine the angle measure of the provided sector using the formula "arc length = (angle measure / 360) x 2r."

c. Half the angle is obtained by dividing the angle measurement by two.

e. Repeat the formula "arc length = (angle measure / 360) x 2r" for the next sector, this time utilising the half angle measure and the same radius as previously.

f. Using the radius and arc length computed in the preceding steps, draw the new sector with a compass or protractor.

Thus, there are a couple approaches that could work to draw a region with half the arc length of the sector. Here are three alternatives:

  • Make use of a protractor.
  • Make use of a compass.
  • Use the formula.
