To calculate: the distance between P and a point on the line, which has all points equidistant from F and T and is perpendicular to the line joining F and T, by the use of a centimeter ruler. The figure is shown below,
Answer to Problem 4WE
The distance between P and A is just less than 5 cm. Also shown in the following figure,
Explanation of Solution
Given information: There are three points F, T and P and a line which is perpendicular to the join of F and T and bisects FT. It is to be found the distance from P to the line perpendicular to the join of F and T.
Formula used: Use a centimeter ruler for measurement of line segments.
Calculation: Hold the ruler in such a way that the zero mark of the ruler coincides with P. Mark the other point that coincides with the line perpendicular to the join of F and T as A. Read the measurement on the ruler which comes out to be just less than the 5th centimeter. Thus PA is just less than 5 cm. Use a ruler to set the distance from the point of the compass needle to the pencil's lead equal to PA. Place the compass needle at P and rotate it about 360 degrees as shown in the figure below.
