Angles & Lines

3.1 - Please click on "DISCUSSION" above and complete the discussion for section 3.1. (be sure to click on Zero V Straight Angle). 3.3 - Please click on "DISCUSSION" above and complete the discussion for section 3.3. (you must click on Why are the not adjacent once in the discussion section of the wiki). 3.2 ***NOTES: While it may not make sense, when rotating clockwise it is given a NEGATIVE measure, and when rotating counterclockwise it is given a POSITIVE measure. The preimage is what you start with and the image is what you end with. Concentric circles - think of a dart board. All of the circles have the same center but their radii are different lengths. Minor arcs are named with TWO letters, major arcs (or semi circles) with THREE. The order of the letters when naming an arc does matter (especially for major arcs). The order of the letters indicates which way to go around the circle!
 * NOTES: Remember when naming angles the order of the letters DOES matter. The vertex must be the middle letter!
