In class today we got to play with protractors and measure angles. We know that a circle is measured in degrees, 360 of them, and that half of the circle is 180 degrees. Half of that is 90 degrees and a right angle. If we know the measure of part of a figure, we can know the other part by subtracting it from 90, or 180, or 360 degrees. We have a LOT of definitions on Geometric Properties TOC 1.
Homework: Study the vocabulary on TOC 1. We will quiz on it when we track back in. (Unless you want to take a vocabulary quiz on Friday)
