Question
To construct a curve of radius r tangential to two intersecting lines (at any angle, as shown on page 18), what initial construction technique is used to find the center (O) of the desired curve?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 18, step 1, states: 'Construct lines parallel to the lines at a distance r away to intersect at O.' This intersection point O is the center of the tangential curve.
