This week we were given 6 polygons and were asked to count the sides, find the angle measure, and the sum of all the angles. We also had a discussion about precise measuring and how measuring is not perfectly accurate.
We also looked for patterns on this chart and used what we knew about the patterns to determine the degree of a Decagon (10 sides) and a nonagon (9 sides).
R-43 write a rule that you could use to find the sum of all the angles for any number of sides polygon.
For example: 112 sided polygon
