Question

There is a distance you could use in parts (b) and (c) of Exercise 2 that would lead to the answer one point in part (c). Estimate that distance.

Short answer

The distance which is slightly below 5 cm can be used.

Step-by-step solution

Step 1. Make the figure that will be required for the estimation of distance.

Make the points $P$, $F$ and $T$ after it forms a horizontal line that will connect $F$ and $T$. By taking the point which has equal distance from the point $F$ and $T$, construct a vertical line that is perpendicular to the horizontal line.

Step 2. Make a circle that touches the vertical line.

Taking $P$ as the center point and make a circle that touches the vertical line. This can be done by using a ruler. Take the centimeter side of the ruler and measure the distance between the point $P$ and the vertical line, which is slightly below 5 cm. Open the compass by using the measurement counted by the ruler and then make a rotation of 360 degrees by putting the needle of the compass at $P$. Name the point $A$ at which the circle is touching the vertical line.

Step 3. Observe the figure and make a conclusion.

The distance which is slightly below 5 cm is the required distance.
