Activities
1. Using the print, calculate the value of the positions identifi by Points 1–11. Point 6, fied
Point 10, and the center point of the 1.25″ radius arc are collinear. It may be necessary ″
to use the formulation of right triangles and trigonometry to calculate certain positions.
Place the values determined into a table similar to the one shown.
