Below are the examples again with the location of the labeled ‘unknown’ object along with the results of the online polls to state your answer. Vertical Angle […]
This week is using the SLOB rule or image shift to determine the location of an object with changes in horizontal angles. Answers from last week Example 1 – diamond object is located to the buccal Example 2 – lightning bolt object is located to the buccal Example 1 Example […]
