 * Learning Goals **

My learning goals for __(Topic/Unit) is:__ Angles

1) How to measure a reflex angle. 2) Learning Vertical Opposites.

To achieve my learning goal(s), I must learn: //How to Measure a reflex angle//

To acquire that knowledge, I will use: //My Textbook, peers and teachers.//

To determine whether I have achieved that goal(s), I will: //Be able to measure a reflex angle.//

To demonstrate that I have achieved my goal(s), I will: //Give an Explanation.//

Greater than 180 degrees. Measure the part that's not the angle. Eg 60 degrees 60 degrees [smaller angle] take that from 360 degrees [full circle] so 300 degrees is the proper angle. Because b° is vertically opposite 40°, it must also be 40° A full circle is 360°, so that leaves 360° - 2×40° = 280° Angles a° and c° are also vertically opposite, so must also be equal, which means they are 140° each. Answer: **a = 140°**, **b = 40° and c = 140°**.
